Nigel Farage is facing fresh questions about an undeclared £5million 'gift' from a billionaire Reform donor today after it emerged he had already discussed a political comeback when he accepted it.Mr Farage has said that he did not have to disclose the seven-figure sum from Thailand-based crypto tycoon Christopher Harborne because it was personal and did not relate to political activity.But the Reform leader himself has admitted he had talked with officials about standing in Clacton at the 2024 general election months before it was made. Mr Harborne made the payment on April 5 that year, according to his own lawyers. But on June 3, less than two months later, Mr Farage told reporters at his campaign launch that Tony Mack, who he replaced as Reform's Clacton candidate, 'knew six months ago that it was a possibility' it would happen.'He knew it was a possibility and is my standing in Clacton going to help 600 other candidates? I think it may well do …and sometimes tough things have to be done you know,' he told reporters.Later that June, a Reform spokesman told the BBC that he had also spoken to Mr Mack, a cabbie, 'six months earlier' about the possibility of Mr Farage taking his place.It comes as the by-election campaign triggered by Mr Farage's resignation gets under way today, with the writ being moved in the Commons this morning.But voters face the prospect of a 'farcical' ballot, featuring none of the main rival parties, after they all refused to fight the contest sparked by Mr Farage's decision to quit amid sleaze accusations.Mr Farage, accusing his mainstream opponents of cowardice, now has joke candidate Count Binface as his chief rival.
