Remember when Sunak promised integrity and accountability? In a government built in and driven by deceit, that was the most egregious of their lies
Johnson loyalists - including former ministers Sir Simon Clarke, Nadine Dorries and Sir Jake Berry - have said they will vote against the report's findings.
It is likely that many more Conservative MPs could abstain, or simply not turn up to the vote, while Labour, the Liberal Democrats and the SNP are all expected to support the committee's findings.
But Conservative MPs still face a dilemma over Monday's vote.
Voting against the recommendations risks alienating local party activists who want Mr Johnson gone, voting for it risks angering his fans, who believe he has been hounded out of Parliament.
Allies of Mr Johnson warned Tory MPs they could face battles with their local parties to remain as candidates at the next election if they back the motion.
Senior Conservative MP Damian Green told the BBC that "deliberately abstaining is not really rising to the importance of the occasion". - that is the correct attitude
The former cabinet minister under Theresa May said he intended to vote to approve the report with a "heavy heart".
Sir Jake - an ally of Mr Johnson - said he was "almost certain that Parliament will vote in favour" of the report on Monday.
But Sir Jake said he would "certainly be one of those in the no lobby opposing this report, whose conclusions he called "wrong".
So far, 15 Conservatives have publicly criticised the committee:
- Johnson ally Ms Dorries suggested Tories who vote for the report should be kicked out of the party - that isn't the correct attitude
- Sir James Duddridge tweeted: "Why not go the full way, put Boris in the stocks and provide rotten food to throw at him?"
- Former Prime Minister Liz Truss told GB News she would not question the integrity of the committee, but added their decision seemed "very harsh".
