It’s hotting up.
Sir Simon letter shows 'final breakdown' of confidence in Number 10
A former Conservative minister has got in touch with our political correspondent Tamara Cohen, following the letter from Sir Simon McDonald this morning.
They said: "It's highly unusual for this sort of intervention by the past permanent secretary of a department.
"It must illustrate a final breakdown of any confidence in a Number 10 operation which appears to be careless of the truth and throw good ministers under the bus to utter what later becomes clear as falsehoods.
"If it illustrates a loss of support from those who really know the inside story of how a government works, it could be catastrophic for those maintaining the present charade."
The ex-minister adds that post-confidence vote, Boris Johnson is safe and unless a sitting minister resigns, nothing much may change.
But they say "this business must bring it closer".
Earlier today, the former Tory justice secretary, David Gauke, tweeted: "A minister can expect to have to go out and defend an unpopular line and that can be uncomfortable. But a minister is entitled to expect that they won’t be lied to by Number 10.
"Of course, at this point ministers must know that there’s a good chance that they are being lied to. And they don’t have to do media interviews."
Imploding.
