Wayne Rooney is believed to have ignored a request from Gareth Southgate to stop drinking and go to bed before he was pictured looking worse for wear.
Southgate, the England interim manager, is understood to have told Rooney and two members of FA staff it was time to finish – only for the captain to later return to the wedding party.
Rooney was then photographed amid claims he carried on drinking until 5am on Sunday.
The incident has led to the FA imposing a strict booze ban and also insisting no future nights out will be allowed while on international duty.
Rooney has apologised “unreservedly” and said the images of him were “inappropriate”.
It could call Rooney’s captaincy and leadership into question but the FA last night moved to distance themselves from reports saying he would be stripped of the armband.
They insist that there is no manager in place to make that decision until Southgate’s future is resolved with his appointment likely to be rubber stamped within a fortnight.
FA chief executive Martin Glenn said: “We’re getting a proper investigation of what actually went on – ‘were there other FA staff involved – yes or no?’ – and we’re doing a review of it obviously.
“It’s disappointing. I think it’s appropriate he apologised because it doesn’t set a great tone for the England captain but, that said, I don’t want to over-dramatise it either.”
