Wes Streeting is preparing to launch a leadership challenge against Keir Starmer on Thursday if the health secretary can secure the support of enough MPs to trigger a contest.

Streeting’s move to force a race has sparked a frantic scramble on the left of Labour to find a candidate to oppose him, with Ed Miliband and Angela Rayner both possible contenders.

The health secretary, who is considered to be on the Blairite right of the party, has been organising an attempt to oust the prime minister for days since Labour’s disastrous election results, despite his friends insisting he did not want to make the first move.
