The scandal-hit former Prime Minister is expected to be hauled before the Commons Privileges Committee for a grilling over whether he deliberately misled MPs about Partygate
The probe into whether Boris Johnson deliberately misled MPs over Partygate faces delays after the Government was accused of being slow to hand over evidence.
The Commons Privileges Committee demanded evidence, including the ex-PMs diaries, WhatsApps, emails and No10 logs more than three months ago for its inquiry into whether Mr Johnson lied about lockdown boozing in Downing Street.
But some of the crucial evidence has still not been handed over, which could hold up the proceedings, sources told The Guardian.
MPs on the seven-strong committee want to summon the first witnesses in the Autumn but no timetable has so far been set out.
