MP for Wycombe Steve Baker has given his full endorsement to a report that found Boris Johnson acted in contempt of parliament during the Covid pandemic.

Mr Baker was the only conservative MP in Buckinghamshire to vote in support of a Privileges Committee report which found that former prime minister Boris Johnson had lied to parliament about lockdown-breaching parties held in Westminster in 2020.

Mr Baker said that he had endorsed the committee's findings "with a heavy heart", adding: "While deliberately misleading the house is bad enough, deliberately misleading the committee, breaching confidence and being complicit in the campaign of abuse towards the committee represent an extraordinary risk to the way we keep this country prosperous, secure and free under the rule of law."

While he declined to comment on growing calls for former mayoral candidate Shaun Bailey to reject the peerage bestowed upon him in Boris Johnson's Resignation Honours List after footage emerged of a party hosted by Mr Bailey in 2020, Mr Baker did say that he believed members of parliament had a duty to set high standards.

"It's a shame when the conduct of a minority brings down the reputation of a political party. Politics requires building institutions that we're proud of and can defend."

Mr Baker also criticised defenders of Boris Johnson who have dubbed the committee findings a 'witch hunt' or 'stitch up'.

"Talk of bias in the committee ignores that the investigation was established under Boris Johnson, Conservative MPs were not told to vote against Harriet Harman and that the majority of members on the committee were Conservative MPs.

"While some have argued that the 90-day suspension is unfair, the report makes it clear that it would have recommended a much lesser sanction if it were not for Boris's complicity in a campaign to undermine the committee, its members and its investigation before the report was ever published.

He concluded: "It is a sorry and terrible situation but there is no doubt in my mind that voting for this report was the right thing to do."

354 MPs voted in favour of the Privileges Committee report in the House of Commons on Monday night, with just seven voting against the motion, including MP for Beaconsfield and Marlow, Joy Morrissey.

Downing Street has not revealed Rishi Sunak's position on the committee's report, with the prime minister among hundreds of Conservative MPs who chose to abstain from the vote.

Following a majority endorsement of the committee's findings, Mr Johnson will not be permitted a parliamentary pass usually given to former MPs for lobbying and visitation purposes.

If he had not resigned as MP for Uxbridge and South Ruislip last week, Mr Johnson would also have been subject to a 90-day suspension from parliament.
