Boris Johnson has “a lot of explaining to do” when he is questioned by MPs on Wednesday about the partygate scandal and comments in the House of Commons that played a role in his downfall as prime minister.

He is scheduled to appear before the Commons Privileges Committee, which is investigating accusations that he misled Parliament.

Dominic Grieve, a former Conservative attorney general, outlined the circle the former prime minister has to square.

“Mr Johnson certainly does appear to have a considerable problem,” he said. “He attended some of the gatherings which were parties, and yet he said that there weren't any gatherings.

“And it's a bit difficult therefore to understand how he didn't know that there had been parties going on at No 10 Downing Street,” Mr Grieve said.

The Sue Gray report has established that widespread rule-breaking took place. And a police inquiry led to fines for 83 people, including Mr Johnson, for attending lawbreaking events.

Opposition parties have accused the former prime minister of misleading MPs about what he knew about gatherings in government buildings during coronavirus lockdowns.

Mr Johnson has always denied misleading Parliament, and told the Commons he believed at the time the events in question were within the rules.

What is the committee examining?

They are investigating whether Mr Johnson misled Parliament, or in parliamentary language committed a contempt of Parliament by keeping it from the task of holding him to account.

The strongest punishment would come after a verdict that he deliberately misled MPs.

Another option for MPs is to find he “recklessly” misled Parliament.

Labour’s Harriet Harman is chairwoman of the Privileges Committee. The other members are Bernard Jenkin, Charles Walker, Andy Carter, Alberto Costa, Yvonne Fovargue and Allan Dorans.

Mr Johnson has always protested his innocence, rejecting any suggestion that he “knowingly or recklessly misled Parliament”.
