European Union auditors said they did not believe that Mr Adams was working on issues related to Mr Farage's work as an MEP.
Nonetheless, Farage swiftly backtracked from his novel idea, "To be clear, I do not want a second referendum, but I fear one may be forced upon the country by Parliament".
But he said Mr Farage had been making a "call to arms" to "mobilise the entire Leave campaign". If Brexit is materially different from what people were sold, then Parliament has a right to keep an open mind.
His comments sparked fury among Brexiteers who accused him of at attention seeking and today he was scrambling to unpick them, saying he does not actually want another vote.
Last month Mr Farage raised eyebrows when he said he was "skint" at 53 years old, despite being entitled to the £90,000-a-year MEPs' salary and living in a £4 million townhouse. That is how deep my distrust is for career politicians. Do we stick with the view that the result will stand or acknowledge the fact that we face this potential threat?'
Appearing on Channel 5's The Wright Stuff, he said: "What is for certain is that the Cleggs, the Blairs, the Adonises will never ever ever give up".
"We should just get on with it".
Deontay Wilder to defend title against Luis Ortiz in March
In taking the fight with fellow unbeaten fighter Ortiz, Wilder has accepted what is widely considered his greatest test yet. November's original fight was postponed after Ortiz failed a drug test .
Mr Farage's initial comments were seized on by Remain supporters, who claimed it demonstrated growing support for a second referendum but some UKIP members were not impressed.
The former Ukip leader suggested a fresh vote would put an end to "whinging and whining" by opponents of Brexit such as Tony Blair, Nick Clegg and Lord Adonis.
The MP for Workington, said: "Labour is not calling for a second referendum, however, I believe there must be accountability over the Brexit process and Parliament must be at the heart of this".
"Promises before the referendum like £350m extra per week for the NHS have evaporated and it looks like the Conservative government is going to give billions of pounds to Brussels for worse trade arrangements than we have now".
Farage said the percentage of people that would "vote to leave next time would be very much bigger than it was last time round", adding that "we may just finish the whole thing off".
Ukip said they were still opposed to a second referendum, although party leader Henry Bolton said he was confident Brexit would win by a bigger margin if another vote were held.
