A new raft of Conservative MPs are poised to send letters of no confidence in Boris Johnson when the long-awaited “partygate” report is published, as the prime minister was pressured by his supporters to oversee a complete clearout of No 10.

The Guardian has learned that senior backbenchers are to move as a collective to force a no-confidence vote in Johnson once senior civil servant Sue Gray releases her findings, which on Tuesday helped trigger a criminal inquiry.
