Lucy Thomas, a Remain Campaign Deputy Director, accused the Brexit architect of supporting the possibility of a second referendum in order to remain relevant and because he “loves a fight”.
She said: “For me, it was a democratic decision, people have had their say and I sort of want to ask Nigel Farage why can’t you accept you’ve won?
“What is it about this that you don’t accept. For me, I’ve known Nigel Farage for probably about 10 years and he just loves a fight, he loves campaigning.”
Asked by Newsnight host Emily Maitlis whether she thought it was about publicity Ms Thomas agreed it was.
She said: “I think he wants to remain relevant.”
Ukip MEP Diane James revealed even his former party were shocked by the move.
When asked when he was thinking she replied said: “‘What was he smoking?’ I think ought to be the next question.”
Ms Thomas said: “I think there are some former Remainers who want there to be a second referendum and have spoken about that.
“When you look at the polls public opinion has not shifted, there is not this missive clamour for a second referendum so I don’t think there is a big push for that.
“You can think about perhaps once the terms are known were people to suddenly be up in arms and say we don’t like these terms we want a second go, but for the moment the polls simply aren’t there.”
Eurogroup president Jeroen Dijsselbloem revealed that there was no clamour in Brussels for a second Brexit vote with EU officials instead simply wanting to know what the UK wants from a deal.
He said: “No one in Brussels is questioning the mandate that the UK Government has coming out of that first referendum, that mandate is quite clear.”
Farage shocked the UK by coming out in support of holding a second Brexit referendum, insisting another vote will put to bed the “ridiculous” anti-Brexit arguments from Remainers.
The former Ukip leader said he believed Britons would once again vote to quit the European Union, just as they did in June 2016.
Nigel Farage also claimed an EU referendum re-run is the only way to end arguments from Remainers wanting to thwart Brexit once and for all.
Speaking on Channel 5’s Wright Stuff, Mr Farage said: “My mind is actually changing on this… What is for certain is the Cleggs, Blairs and Adonises will never ever give up.
“They will go on whinging, whining and moaning about the whole process.
“So maybe, just maybe I’m reaching the point of thinking that we should have a second referendum on EU membership.”
The Brexiteer said a second vote would kill off the issue for a “generation” and send Tony Blair to “total obscurity”.
“I think if we had a second referendum on EU membership we’d kill it off for a generation.
“The percentage that would vote to leave next time would be very much bigger than it was last time around.
“We may just finish the whole thing off and Blair can disappear off into total obscurity.”
