Asked if he earned any of the money used by his partner to buy the house, Farage told reporters on Friday: “No. No, no, no, listen, can I be clear about this. The money was legally hers, the estate agents and everyone did the know your customer rule checks.”

He added: “I don’t have any financial stake in it whatsoever, other than she lets me stay there but then given that I’m her partner that’s not really that unusual.”

Pressed over whether he had given his partner funds at any point, the Clacton MP said: “I have given every answer to this I want to give.

“I’ve even been this week to a King’s Counsel tax expert and paid a lot of money to make sure that everything we’ve done is legal and right.”

Asked why he had sought expert tax advice, Farage said he was “really concerned” that some media reports were “beginning to stray into libel territory”.

“So I have now done everything I can at every level to prove that everything that’s been done is legal, correct and right,” he added.

“It’s been a very expensive week.”
