Nigel Farage has called on the Government to go in a fiery swipe at Boris Johnson.
The GB News presenter took aim at the PM over his handling of Chris Pincher, after No 10 were accused of not telling the truth over their knowledge of the MP's conduct.
Work and Pensions Secretary Thérèse Coffey had previously stated the PM was "not aware" of sexual misconduct allegations facing Mr Pincher, only to seemingly be contradicted by Downing Street just hours later.
Nigel described the situation as "one of the biggest crises of confidence in Government and the people that run it that I've ever seen in my lifetime".
Mr Pincher has been accused by two men of drunkenly groping them at an event for the Conservative Friends of Cyprus at the Carlton Club in Piccadilly.

Mr Pincher has since had the Tory whip removed, and has pledged to co-operate with the inquiry into his drunken behaviour.
Nigel told his Twitter followers: "This is a Government built on lies.
"They think they can lie their way out of any situation.
"Is it any wonder there has been a quarter of a third of Conservative 2019 voters who now think the Prime Minister is a liar?
The Prime Minister is facing fresh sleaze accusations following sexual misconduct claims aimed at Chris Pincher.

"As David Cameron said, he's a greased piglet, you can never get hold of him, he always gets away, this time it can't happen.
"If he stays, the Conservatives are headed for the biggest electoral cataclysm since 1997, it might be even worse than that."
The former Brexit Party leader has called on members of the Cabinet to stand down in order to retain personal credibility.
Nigel warned them that their respective hopes of potentially going onto became party leader may be scuppered as a result of their continued association with Mr Johnson.
He said: "Now is the time to find out whether the party can be saved, or if it's going to be dragged down with [Boris] Johnson and a bunch of college kids running No 10.
"If no one in that Cabinet is prepared to stand down as a matter of principle, my view is, they will all automatically disqualify themselves from being fit and proper to be the next leader as and when that happens."
Nigel added that he expects a leadership contest to take place "at some point this year".
