The EU has denied "insulting" suggestions that European Commission president Jean-Claude Juncker was drunk at this week’s NATO summit, saying he was suffering from sciatica.
The 63-year-old was seen to be unsteady on his feet at the summit dinner in Brussels on Wednesday evening, and had to be helped away in a wheelchair.
The prime ministers of the Netherlands and Portugal, Mark Rutte and Antonio Costa, helped prop him up.
Commission spokesman Margaritis Schinas said it was more than tasteless for the press to write insulting headlines by exploiting President Juncker’s pain.
I don’t think this is elegant and I don’t think this is fair, he added.
Asked whether Mr Juncker had mixed painkillers and alcohol, Mr Schinas replied: No he didn’t – at least I am not aware of this happening.
The president had suffered a very particularly painful attack of sciatica accompanied by cramps, Mr Schinas said.
The president has himself publicly stated that this sciatica affects his ability to walk, he continued.
That was unfortunately the case Wednesday night.
He is taking medication and feels better.
Sciatica occurs when the sciatic nerve, which runs from the hips to the feet, is irritated.
Mr Juncker carried out a full programme at NATO and the European Commission on Thursday, Mr Schinas said, and will stick to a very demanding agenda next week, including a trip to China and Japan.
The German government weighed in on Friday, with spokesman Steffen Seibert saying Berlin has a very high level of confidence in the Commission president.
Mr Juncker, whose five-year term at the head of the commission ends next year, has faced questions before about his public demeanour.
At the opening of a summit in the Latvian capital Riga, in 2015, he kissed leaders on the head, fiddled with their ties, saluted, and slapped them not just on the back but also on the stomach, chest and face.
He also teased the Hungarian prime minister, Viktor Orban, over his strongman reputation, greeting him jokingly as dictator.
