Nigel Farage celebrated his last night as Ukip leader with a late-night skinny dipping session off Bournemouth pier, it has been revealed.

Key financial backer Arron Banks told BBC Radio 4's Any Questions? show on Friday night that he and Mr Farage had stripped off their clothes and jumped in the sea after a late-night drinking session on Thursday.

But Mr Farage claims he "kept his underpants on".

The MEP, who has been replaced by Diane James in the party's top job, said he headed into the sea off Bournemouth because it was "warm and humid".

Despite claims by Mr Banks that they got naked, Mr Farage said his modesty remained intact.

Multi-millionaire businessman Mr Banks made the revelations after challenging claims during the political talk show that Mr Farage might stage another comeback as leader.
