Boris Johnson last night admitted he’d “crashed the car into a ditch” as he faced furious Tory MPs over his U-turns on sleaze.
Conservatives were tight-lipped and told not to speak to the media as they left a terse meeting of the 1922 Committee of backbenchers.
But one revealed to Bloomberg that the PM told them: “On a clear road I crashed the car into a ditch”.
Another told the BBC ’s Laura Kuenssberg the coughing PM “looked weak and sounded weak”, adding: “Authority is evaporating”.
It came after MPs backed plans to ban MPs from taking “parliamentary consultant” jobs in a U-turn by Boris Johnson.
But Tories watered down Labour ’s hope that they would set up a hard deadline to pass new rules by mid-February.
And analysis by the Guardian suggests that focusing on parliamentary consultants - a wording taken from an independent report in 2018 - will only affect around 10 Tory MPs.

Despite Labour blasting the “watered-down” plans, the second jobs crackdown - and the U-turn that brought it about - has enraged many Tory back benchers.
Government benches in the Commons were the emptiest they have been in recent memory as Boris Johnson faced the music at PMQs.
And the Mirror was told a queue of Conservative MPs was spotted waiting to speak to the PM in his Commons office yesterday afternoon.
Foreign Secretary Dominic Raab today insisted standards reforms were “not being kicked into the long grass”, with a new set of draft rules due by January 31.
He added: “It went through overwhelmingly so we can now deal with the problem”.
But a former Cabinet minister said the row had been handled poorly and damaged the Government.
Robert Jenrick said the "checks and balances around the Prime Minister" and advisers should have warned him that his plans to overhaul the standards system were not going to work.
He told ITV's Peston: "It has been a very difficult two weeks and almost everyone involved would agree that it's been handled poorly by the Government and it's damaged the Government to an extent, and it's damaged Parliament as well.
"We need to take action now to restore a degree of public trust in the standards in public life, and what you would expect from a Member of Parliament."
During Prime Minister's Questions, Mr Johnson was rebuked by the Speaker, Sir Lindsay Hoyle, for trying to turn the focus on Keir Starmer.

The Government managed to win an amendment to allow proposals on the banning of paid consultancy roles to go ahead, but just 297 MPs backed the move - with many Tories abstaining.
Four Conservative MPs rebelled to support Labour's motion - Peter Bone (Wellingborough), Philip Hollobone (Kettering), Nigel Mills (Amber Valley), and Dan Poulter (Central Suffolk and North Ipswich).
Mr Johnson also faced the Commons Liaison Committee of senior MPs, where he admitted mistakes had been made.
It was all prompted by a botched attempt to save former MP Owen Paterson from suspension for breaches of lobbying rules.
Yesterday Mr Johnson finally admitted the initial effort to shield Mr Paterson had been an error.
"In retrospect it was obviously, obviously mistaken to think we could conflate the two things and do I regret that decision?
"Yes I certainly do,” he said.
Speaking after the vote, Labour leader Sir Keir Starmer told broadcasters: "We put forward a plan of action to clean up politics and strengthen standards in politics.
"And if you can believe it, after two weeks of Tory sleaze and corruption, the Prime Minister whipped his MPs against that plan of action, and, frankly, he just doesn't get it."
