The incident was uncovered by the UK's AI Security Institute, which was set up by then-prime minister Rishi Sunak almost three years ago to test advanced models from major tech companies. In a blog post, the institute detailed a cybersecurity challenge it had posed to OpenAI's GPT-5.6-Sol model and Anthropic's Mythos 5, which have both been involved in recent hacks of other companies. Read more:OpenAI admits its models went rogueAnthropic reveals its AI hacked three firms Several instances saw both models take "autonomous, unsanctioned action" on the live internet, where real organisations and people were targeted. The "most serious case" involved Mythos 5, which tried to insert malicious code into the open-source software development platform GitHub, where users store, share and collaborate on projects. To do so, it created fake online identities to try to pressure a human into granting it access and approving its code. The human caught and refused to approve the malicious code, and no real-world harm has been identified, but the institute nonetheless has sounded alarm bells over the nature of the incident. "This is the first time we have seen risks around autonomy and deception manifest this clearly, without specific prompting, in the real world," it said. There were 19 instances of "unauthorised action" in total across 122 tests, with Mythos 5 behind 17 of them. How have the companies responded? Anthropic has said it is working closely with the UK institute to obtain more details. It has previously said only collaboration between AI companies will help address the risks posed by the technology. OpenAI addressed the institute's test in a blog post, adding: "We are committed to working across the industry to strengthen ​shared practices for conducting high-risk evaluations safely, including convening stakeholders such as national AI institutes, independent evaluators, other AI ⁠labs, and other groups in the coming weeks." The institute's report underscores concerns around the lax safeguards around the testing of the most powerful agents, known as frontier models. They are more powerful than those behind public-facing products like ChatGPT. GCHQ's National Cyber Security Centre said recent incidents "are a serious reminder of the risks AI poses". Its chief technology officer, Ollie Whitehouse, said they "must be developed and used from the outset with strong safeguards, real-time oversight, and clear plans for responding when the unexpected happens". The AI Security Institute was established at a time when world leaders were seeking to find common ground on AI regulation. Since then, a consistent approach has failed to materialise.

A new version of the 1977 film – titled Star Wars: Gobaith Newydd – is set to be broadcast on the Welsh-language TV channel S4C from Christmas Day onwards to celebrate the saga's 50th anniversary next year. The announcement was made at the National Eisteddfod, the largest cultural festival in Wales. The film, directed by Ellyn Stern and produced by Lucasfilm and Disney in collaboration with S4C and the Welsh government, features the voices of several well-known Welsh actors, including Primetime Emmy winner Matthew Rhys as Han Solo and Notting Hill star Rhys Ifans as Obi-Wan Kenobi. Aimee-Ffion Edwards, perhaps best known for her roles in Peaky Blinders and Slow Horses, voices Princess Leia, while Osian Morgan, who has appeared in TV shows such as Waterloo Road and Emmerdale, is Luke Skywalker. Mark Lewis Jones, who appeared in 2017's Star Wars: The Last Jedi – the second film in the franchise's so-called sequel trilogy – takes on the role of Darth Vader. 'A beautiful lyrical language' Welsh First Minister Rhun ap Iorwerth hailed Star Wars as "one of the most influential films of my childhood" and insisted the film's appeal "shows no sign of waning, captivating audiences to this day". Mr ap Iorwerth said: "To see a Welsh language version of this iconic film, using the talents of some of our best actors, is fantastic. We already produce world-class TV and film here in Wales, and I'm really looking forward to seeing Star Wars in Welsh later this year." Lucasfilm co-president Lynwen Brennan, who was born and raised in Wales, said the country had a "rich history of storytelling and a beautiful lyrical language". Ms Brennan said she was "so thankful" Star Wars was being translated into Welsh, adding: "Welsh speakers will finally be able to enjoy the film in our native language, and my hope is that it will have the same emotional impact as if you were watching the film again for the first time." Last year, Wales's government set a target of having one million Welsh speakers by 2050. It came after figures from the latest census in 2021 showed a fall in the number of people who could speak the language compared to a decade earlier. An estimated 538,000 people in Wales – or 17.8% of the population – said they could speak Welsh, compared to 562,000 in 2011 (or 19% of the population).

In 1979, a full-size Millennium Falcon – the iconic starship primarily piloted by Harrison Ford's Han Solo and the Wookie Chewbacca in the original trilogy – was built at Pembroke Dock for the 1980 sequel Star Wars: The Empire Strikes Back. Meanwhile, scenes from the Disney+ series Star Wars: The Acolyte, as well as Lucasfilm's 1988 film Willow – and the 2022 sequel TV series of the same name – were shot on location in Wales.

Andy Burnham has blocked cuts to sentences – also known as early release – for rape and serious child sex and grooming offences, which will be welcome news to many. Politics Hub: Follow the latest Others, though, will be left wondering: what about me, or my case? Why is my perpetrator, some of them who will be in prison for really serious crimes, able to be freed early and not others? PC Andrew Harper's widow, Lissie, has called the announced review changes "disgusting" and an "utter betrayal". Thames Valley Police Federation, the force where PC Harper served, said they are "outraged that the justice secretary and the prime minister have decided that killing a police officer in the execution of their duty is somehow less serious than other offences deemed too dangerous for early release". The Domestic Abuse Commissioner, Nicole Jacobs, has said the government are putting "lives at risk" by not excluding domestic abuse perpetrators in the way that rape offenders and others are. "While this will be well received by some victims, most will not fall within those categories, and exclusions alone cannot guarantee victim or public safety," said Claire Waxman, the Victims Commissioner. The problem is, much of this is about pragmatism and politics. There is a perception that the general public don't care about prisons until it's a conversation about public safety and perceived injustice. This is exactly that. How did we get here? The latest row over this policy happened only days after Burnham became prime minister. He probably felt he had little option but to look again – ironically at plans which were made law under Sir Keir Starmer's government earlier this year, following an independent review of sentencing policy. Burnham has long been a critic of how previous governments have failed victims of injustice or covered up scandals. But he will also have been told that scrapping the plans altogether wasn't an option because of prison overcrowding. The male prison estate is operating at around 97% capacity still, even after numerous "emergency" or "temporary" measures, releasing tens of thousands of inmates early, under successive governments. One prison governor told me their usual "summer lull", as courts start to shut down for August, isn't happening this year. "What does this do to capacity by Christmas?" they asked. Remember, in 2024 there were just 100 free spaces left across England and Wales. Police custody suites were regularly used as alternative cells. 'A risk mistakes will be made' But there are fears too that "there is a risk mistakes will be made", according to one prison service source, with fast turnaround sentence recalculations (again) by an already stretched service. The first tranche of releases wasn't due until 2 September, but the prison and probation service had a while to plan for that date. It's now been delayed until 1 October, but with new exclusions, which could become complicated. Someone could be serving a sentence for varying offences, and things could be missed, is the worry. Probation will now only have around six weeks for release planning, once the sentences have been recalculated. Read more from Sky News:Woman who stole £300k from pensioner is jailedMan jailed after falsely claiming electric car was out of control A reminder – the Sentencing Act 2026, which became law earlier this year, meant prisoners serving standard sentences in England and Wales could be freed after serving a third of their sentence, rather than half, if they didn't break prison rules or commit further offences in jail. The rest would be spent on supervision in the community, using electronic tagging. More serious criminals, including those convicted of sexual and violent crimes, would have been eligible for release from prison after serving half of their sentence, rather than two-thirds, as is typically the case at the moment. 'Not the end of the conversation' This announced review now excludes inmates serving sentences for crimes like rape and grooming offences. But people who are in prison for a crime such as manslaughter can in theory still be released after serving half of their sentence. What this has to be about is human consequences and confidence in the justice system. For victims of rape, that's historically been a huge hurdle. The prospect that their demands are being listened to with these changes will be something. But even a lawyer representing abuse and grooming victims – the perceived beneficiaries of the review – tells me: "This should not mark the end of the conversation." "Victims of other serious violent offences also deserve confidence that sentences imposed by the courts will be served as intended," they said. This issue has troubled governments for years now. Burnham will be viewed by some as a new PM who acted decisively and who cares about victims and injustices. But what's already clear is that the outcome of this review is being seen by others as an injustice in itself.

The Gunners remain in talks with Newcastle over a deal for the 28-year-old, who would be joining a group of midfielders which includes Declan Rice, Martin Zubimendi, Martin Odegaard, Mikel Merino and Myles Lewis-Skelly. So where and how would he fit in? No 6 or No 8? Guimaraes can play as a deep-lying midfielder or a more advanced No 8. He explained his preference for the latter position in an interview with Sky Sports in October 2022, when he was being used by former Newcastle boss Eddie Howe in the No 6 role. "To be honest, if you ask me this question, I have to say I prefer to play at No 8, but I think my role here, at No 6, is exactly what the team needs," said Guimaraes. "It is to take the ball out, to do some passes, to find the wingers and the strikers. Transfer Centre LIVE! | Arsenal news & transfers🔴⚪Arsenal fixtures & scores | FREE Arsenal highlights▶️Got Sky?

Latest Sky Sports deals or stream PL games with no contract📺 "I can play both positions, but Eddie has a choice to make and, for me, the most important thing is just to play and to help Newcastle get the three points. I think my best position is at No 8 but I can play at No 6. It's not a problem for me." Guimaraes ended up playing in his favoured role for Newcastle after Sandro Tonali took over at No 6, but his flexibility, and willingness to put the team first, will doubtless appeal to Mikel Arteta, who loves players able to slot into different positions. Guimaraes' versatility shines through when breaking down his minutes played by position in the Premier League. The graphic above shows he has played most of his minutes for Newcastle at the base of midfield but also highlights his ability to play as both a right and left-sided No 8, providing further evidence of the flexibility he can bring to Arsenal in terms of how he is used. The options he'd give Arteta Even when ostensibly starting as Newcastle's No 6, Guimaraes was platformed to attack. "With the way we are playing, Dan Burn is at left-back, so he can stay in the middle and I can go and be another player to help the attackers," he added to Sky Sports in 2022. Guimaraes finished that season with four goals and five assists in the Premier League for Newcastle, despite playing as the No 6. He was even more productive in the following campaign, scoring seven goals and providing eight assists in the same role. In total, the Brazil international has contributed an impressive total of 30 goals and 25 assists in 153 Premier League appearances for the club, underlining the extent of his attacking threat. Arsenal have plenty of full-backs capable who could tuck inside to allow him to get forward from the No 6 position. But another way to maximise Guimaraes's attacking qualities in a box-to-box role would be to use him as part of a double pivot. Rice could be the perfect foil. The 27-year-old spent most of last season playing as Arsenal's left-sided No 8, with Zubimendi playing at No 6. But he finished it playing further back, on the right of a double pivot with Lewis-Skelly, who impressed after his late-season move into midfield. Rice excelled alongside the youngster. Like Guimaraes, he has the energy to get up and down the pitch as a box-to-box midfielder but he is also tactically aware and disciplined in his positioning. Even before he was moved back into a double pivot last season, Rice often provided cover for Zubimendi, who was able to score five Premier League goals while playing as Arsenal's No 6. Using Guimaraes and Rice in a double pivot would allow Arteta to deploy one of Martin Odegaard or Eberechi Eze as a pure No 10. In the event of Rice being unavailable, or simply needing a rest, he could even use both players as No 8s ahead of Guimaraes at No 6. If Arteta wanted to go in the opposite direction and prioritise physicality over flair, he could sacrifice a playmaker for Zubimendi and push Guimaraes forward, into the right-sided No 8 role in which he spent much of the last two seasons for Newcastle. A midfield trio of Guimaraes, Zubimendi and Rice might not appear the most attack-minded but it would certainly allow Arsenal to win most physical battles in central midfield. It should also be noted that Guimaraes actually profiles similarly to Odegaard as a passer. Guimaraes made almost exactly the same number of line-breaking passes per 90 minutes as the Arsenal captain last season. His average of 8.6 put him well ahead of either Rice or Zubimendi. He also directed a similar percentage of passes forward to Odegaard, and was in fact more efficient in terms of forward-pass accuracy. The numbers reflect a capacity to unlock opposition defences which could mitigate Odegaard's absence, at least to some extent, while providing another source of creativity from central midfield. Would others lose out? The arrival of Guimaraes would inevitably raise questions about some of Arsenal's other midfield options but is easy to see the logic behind their efforts to land a player of his quality. Last season, the distribution of midfield minutes was too heavily weighted towards Rice and Zubimendi, both of whom would benefit from a lighter load having played more than 4,000 minutes. Arsenal's overreliance on Rice and Zubimendi was partly due to injuries. Odegaard and Merino both had long spells on the sidelines, along with Kai Havertz, who can also play in midfield. But it also reflected Arteta's lack of trust in alternatives such as Christian Norgaard, who is expected to join Everton. Norgaard's exit would free up a space in the squad for Guimaraes but Arsenal may still have work to do to reduce numbers, with Ethan Nwaneri and Fabio Vieira having returned from their loan spells at Marseille and Hamburg respectively last season. Lewis-Skelly, meanwhile, may find himself bumped down the pecking order having finished last season as a midfield starter ahead of Zubimendi. But Arsenal played 63 games last term and will be targeting silverware on multiple fronts again. The level of rotation required in that context, and the potential for injuries and absences, should still allow opportunities for Lewis-Skelly in midfield. But the reality is that Guimaraes, valued at £80m by Newcastle, would not be arriving to play a supporting role.

Data from an organisation that monitors antisemitism in the UK has revealed a spike in incidents, with 1,926 recorded from January to June 2026. Assaults, arson attacks and threats were among the incidents recorded by the Community Security Trust (CST) - with the total up by a fifth on the first half of last year. After the stabbings of two Jewish men in Golders Green, north London, in April, the CST said it recorded its highest daily number of antisemitic incidents of the year so far. A total of 71 incidents were recorded in the three days following the stabbings on 29 April - 16 of which directly referenced the attack, the organisation said. The week following 28 February - the date Israel and the US began their war on Iran - saw a 71% jump in antisemitic incidents in the UK compared with the week before, from 52 to 89, according to the CST. The charity also noted that a series of alleged arson attacks were carried out across Jewish sites in London, including on four community ambulances, throughout the first months of the year. It defines an antisemitic incident as any malicious act aimed at Jewish people, organisations or property, which shows evidence of antisemitic motivation, language or targeting. Greater London sees highest incidents According to the CST, the area with the highest number of reported antisemitic incidents in the first six months of 2026 was Greater London with 994. Greater Manchester saw 222, while Scotland as a whole saw a reported 76. Hertfordshire was reported to have 73, West Yorkshire had 64, Essex saw 58, and Northumbria had a reported 39. Assaults, threats and abusive behaviour The CST recorded 135 assault incidents during the first half of the year - the highest six-monthly total figure in this category ever reported to the organisation. Other forms of offences reported included 15 instances of antisemitic literature, 126 threats, 77 instances of damage and desecration, and 1,572 instances of abusive behaviour. Of the 77 counts of damage and desecration, there were seven cases of arson or attempted arson, the CST said. 'Appalling numbers' The government's independent adviser on antisemitism, Lord John Mann, said the figures "demonstrate that anti-Jewish racism in the UK remains at an all-time high and continues to pose a significant threat to our democracy". He added: "It is especially concerning to see the nature of antisemitism in the UK becoming increasingly violent, from the stabbing of two British Jews in Golders Green, to a series of arson attacks against synagogues and Jewish-linked properties." See more from Sky News:Trump sells posts to highest bidderMurderer keep family in agony Policing and crime minister Sarah Jones said: "Behind these appalling numbers are people living in fear just for being who they are. "Antisemitism goes against our country's values, and I will do everything in my power to protect our Jewish communities." She added the government is investing £250m to boost policing in Jewish neighbourhoods, and said: "We must never stop fighting to rid society of this evil." The Jewish Leadership Council said the figures "are no surprise" and that "Jews continue to face intolerable levels of hatred in our country and that should shame us". A spokesperson for the body of Jewish organisation around the UK added: "The prime minister has pledged a zero-tolerance approach to antisemitism. We welcome that commitment, but those words must be matched by action."

Warning: This article contains references to self-harm. A spokesperson for the Miami-Dade Sheriff's Office told Sky News's US partner network NBC News they responded to the home of the former gossip journalist after receiving reports of someone "who was livestreaming acts of self-harm on social media". The statement did not name Hilton but was sent in response to an inquiry about him. A later statement from the sheriff's office said the person was "safely recovered" and taken by Miami-Dade Fire Rescue to a local hospital, where he was receiving medical attention. It said deputies spoke to family members at the scene, who confirmed the person had been alone inside the home. The video, streamed on TikTok on Tuesday, appears to show Perez covered in blood with cuts on his arms and torso, while drawing a knife across himself. The footage has been taken down. Dante Rusciolelli and Rebekah Kochan, co-chiefs of talent management firm Golden Artists Entertainment - which represents Hilton - said they are "aware of the concerning content circulating online". "At this time, we have not been able to make direct contact with him, despite our ongoing efforts to reach him," they said. "Our primary concern is Perez's health and well-being, as well as the well-being of his family."

It comes after Prime Minister Andy Burnham responded to backlash to the plan, which was initiated by the Starmer administration with the goal of easing prison overcrowding, by putting it on pause and launching an "urgent review". Politics Hub: Follow the latest Mr Burnham has also delayed the start of the scheme from September to October and said he "wanted to go even further", but it was not possible without the prison system collapsing – putting the public "at much greater risk". He is also seeking to assure the public that offenders will face tighter community supervision, including new GPS monitoring for rapists to restrict movements. The policy has been controversial since the outset but returned to prominence earlier this month when it emerged a policeman's killers may be among those eligible for early release. PC Andrew Harper was killed in 2019 while responding to a quadbike theft in Berkshire. When teens Albert Bowers, Jessie Cole, and Henry Long tried to escape, his ankles got caught in a getaway car's towrope loop, and he was dragged along a country road for a mile. While Long, who was driving the vehicle, was jailed for 16 years for manslaughter and will not be eligible for early release, Bowers and Cole were jailed for 13 years for manslaughter and will be eligible to be freed under the scheme after serving half their sentences. PC Harper's widow, Lissie Harper, had called for the prime minister to intervene. In a statement on Monday night, she condemned the fact that two of her husband's killers remain eligible as an "utter betrayal". 'I will not be able to forgive' Ms Harper said: "What abhorrent message does this send? How dare ministers say the killing of a police officer is not enough of a 'sickening crime' that deserves the stiffest of punishments." Bowers and Cole had "robbed us of our future" and "should remain in jail", she added. "This is an utter betrayal – and it's one I will not be able to forgive or forget," she said. Thames Valley Police chief constable Jason Hogg also said he was "beyond disappointed", while Aileen O'Connor, chair of the Thames Valley Police Federation, said she was "absolutely outraged". PM: I wanted to go further The prime minister said public safety is his "top priority", and he understands the "anger, anxiety and distress that's been caused" by the early release scheme. Despite the announcement regarding rapists and child sex offenders, Mr Burnham said, "I know there will still be concerns about other offenders having their sentence shortened". "That's why we will also be introducing much tougher community measures," he said. "There will be a presumption that all offenders are tagged, longer periods of supervision and tough new rules, including restriction zones for offenders." Read more from Sky News:'Worrying decline' in adoptive familiesRacist abuse of NHS staff 'getting worse' The government has also announced a £10m package of support to provide better trauma-informed contact, with a new national helpline to contact all affected victims. Mr Burnham also hit out at the previous Tory governments for not having invested in the prison estate, with adult male prisons now at 98% capacity, and pledged "the fastest prison-building programme since the Victorian era". He has also asked Justice Secretary Alex Norris to look at how the UK can remove foreign offenders faster, review outdated Imprisonment for Public Protection (IPP) sentences, and free up space in women's prisons. How did we get here? Under changes in the Sentencing Act around 6,000 offenders were set to be freed in September after serving a third of their sentence – rather than half – as part of efforts to reduce overcrowding. Prisoners serving sentences of four years or more would be eligible for release at the halfway point of their term, rather than two-thirds. 'U-turn doesn't go far enough' The Conservatives had voted against the scheme and said the "U-turn" from Mr Burnham doesn't go far enough. Shadow justice secretary Nick Timothy said "the trauma of victims being told their abusers may be released can't be undone", while Reform UK branded the scheme "disgusting".

Uncertainty over LIV's final tournament of the season, which takes place on August 27-30 in Michigan, has lingered, major winner Martin Kaymer previously suggesting that he did not think the event would occur, giving it just a five per cent chance of happening. The creation of LIV Golf sent shockwaves through the golfing world following its inception in 2021, where it was positioned as a rival to the PGA Tour and DP World Tour. Jon Rahm tight-lipped on whether he will be in LIV Golf in 2027Live golf on Sky Sports this weekGet Sky Sports or stream golf with no contract But now, the future of the breakaway golf league beyond the end of this season also remains in doubt after the Saudi Arabia Public Investment Fund confirmed in April it is ending its funding for the series. LIV is now bidding to seek alternative investment. While there is so much up in the air, Smith remained optimistic that the season would draw to its scheduled conclusion in Michigan. "We have been told to prepare as though it's going ahead. So we are expecting it to happen," he said. "I'm really unsure, but we had a great year there last year in Detroit, and we're hoping we get back there. "It is a great golf course, a great venue, and the crowds really turned up as well. I would be disappointed if it wasn't." Asked whether he has made preparations to join another Tour, Smith said he has not started to make those movements and is instead focused on "keeping the team alive". "I am a positive guy, so I've made no effort to go seek anything else," he said. "I don't really understand what is going to happen. I think it's all up in the air. I know that the LIV team is working hard to get us to play next year and working hard for us. They do a lot of hard work behind the scenes. "I want it to work to be honest. It is great fun out here. The team that we've got, I feel like we make each other better, better people and better golfers as well. "I would hate to see it go away." Smith did concede that there was a possibility that he could be left with little option but to return to the PGA Tour. "I mean, if it was the only option, I think that's where everyone would want to be for sure, 100 per cent," he added. "It would go back to old times." DeChambeau leads player meeting on LIV Golf's future Following Smith's comments, the LIV Golf players had a meeting which was reportedly led by DeChambeau as they discussed the future of the league. According to Richard Bland, DeChambeau said the next couple of weeks will be when the full picture of the situation comes to light. However, he is "positive" with what they are hearing is going on. "Bryson just ran through what he knows, and obviously, we're trying to do it as a group, but we're individuals as well, so I think the next two to three weeks is going to be where it's at," Bland told The Athletic. "We're in this together; we're fully backing Scott (O'Neil). I think probably in the next two to three weeks we'll have a bigger picture. "We're just in that kind of stage at the minute that we're positive with what's going on, but we just need everything to be fully signed off so you can go forward." And on whether the Team Championship will take place, Bland added: "I don't know. We have just got to wait and see on that." Lee Westwood was less forthcoming when asked about his insight into the player meeting and said: "No, I'm not talking about it. Blandy shouldn't be either."
