Mr Streeting has arrived in Downing Street for a showdown meeting with the PM over the coup attempt in the wake of disastrous local elections.

He opted to stride in through the famous black door instead of one of the more discreet entrances.

The PM’s band of allies have dismissed the encounter as a ‘quick coffee’, jibing that Mr Streeting does not have the numbers or the ‘nerve’ to challenge.

But the peril remains – with claims unions are poised to say Sir Keir cannot fight the next election.

Ominously, the next batch of Mandelson documents is due to be released as early as next week.

Manchester mayor Andy Burnham and Angela Rayner are both circling as the question of who will succeed Sir Keir dominates MPs’ discussions.

High drama at Westminster yesterday saw four Labour ministers resign, saying they no longer had confidence in the premier.

The number of Labour MPs calling for him to go rose to 90, and Home Secretary Shabana Mahmood was forced to deny she is on the brink of quitting after telling the PM to set out a timetable for his departure.
