The House of Commons privileges committee is expected to accuse Boris Johnson of misleading parliament regarding the Partygate scandal, in which he was fined for breaking coronavirus rules.
The committee has the power to recommend a suspension from parliament, but Johnson
's resignation as an MP reduces the sting of this sanction.
Other possible reputational hits include admonishment or censure by the Commons, or criticism of Johnson
's allies in parliament.
The committee could also effectively ban Johnson
from the parliamentary estate.
The ultimate goal is to hold politicians accountable for their actions, and the outcome of the committee's report will be closely watched.
