Allies of Boris Johnson have been criticised for putting “improper pressure” on the privileges committee, which examined allegations that he lied to MPs over partygate.

The committee highlighted comments by senior MPs including Nadine Dorries, Sir Jacob Rees-Mogg and Priti Patel, along with Lord Goldsmith, a serving minister.

“Those Members did not choose to engage through any proper process such as the submission of letters or evidence to our inquiry, but by attacking the members of the committee, in order to influence their judgment,” the committee’s report said.

It said that their aim was to “influence the outcome of the inquiry”, “impede the work of the committee by inducing members to resign from it”, and “discredit the committee’s conclusions if those conclusions were not what they wanted”.

The report added: “The committee is particularly concerned about attacks mounted by experienced colleagues, including a serving minister of the Crown, a former leader of the House and a former secretary of state for digital, culture, media and sport.”
