Boris Johnson submits evidence before Partygate grilling

Boris Johnson has submitted evidence to MPs investigating whether he misled Parliament over Covid rule-breaking parties in Downing Street.

The former prime minister, who denies misleading MPs, wants his defence to be published as soon as possible.

However, it is expected the MPs on the Privileges Committee will want to study the contents before making it public.

Mr Johnson will be questioned by the cross-party committee in a televised session on Wednesday.

In an initial report earlier this month, it found Mr Johnson may have misled Parliament multiple times.

Wednesday's session, which could last up to five hours, will be crucial in determining his political future.

If Mr Johnson is found to have misled Parliament, the committee will consider whether this was reckless or intentional, and recommend how he should be punished.

MPs would have to approve any sanction, but potential punishments range from ordering him to apologise to suspension from the Commons. If he is suspended for more than 10 days, this could trigger a by-election in his constituency.

Downing Street sources say MPs will be given a free vote, meaning they will not be told to vote either for or against the sanction.

The Privileges Committee, which is chaired by Labour's Harriet Harman, is made up of seven MPs - four Conservatives, one more Labour MP and one SNP MP.

Reports of gatherings in government buildings during Covid lockdowns first emerged in late 2021.

On several occasions, Mr Johnson, who was then prime minister, told the Commons the rules had been followed.

He later admitted his original statements had since proved incorrect. However, he has insisted he believed them to be true at the time and that he had been assured this was the case.

An investigation by senior civil servant Sue Gray found widespread rule-breaking had taken place and a police inquiry led to 83 people, including Mr Johnson himself, being fined for attending events.

The Privileges Committee's initial report said it had seen evidence that "strongly suggests" Covid rule breaches would have been "obvious" to Mr Johnson.
