The Observer has run with news of senior Tory MPs blasting ex-prime minister Boris Johnson, quoting one describing him as going “full Trump”. The paper claims that support for the embattled ex-leader is draining away in the wake of his response to the probe into whether he misled MPs over parties at No 10.

It reports that several Conservative grandees reacted with ‘disbelief’ as Mr Johnson questioned the work of a cross-party Commons committee investigating the issue. Allies of the former Prime Minister accuse the committee of staging “a political show trial”.
