Chris Pincher, a Conservative MP, faces an eight-week suspension from the Commons after being found guilty of groping two men at a London club in 2021.
The incident was deemed "completely inappropriate" and an "abuse of power" by Parliament's standards committee.
The suspension will need to be endorsed by the full House of Commons, which would trigger a recall petition process and potentially lead to a by-election in his constituency.
The MP has already stated he will reflect on the report's conclusions but will not comment further.
He has apologized for his behavior and sought professional help.
The incident occurred after an event where Pincher had been invited to speak as a former minister, and he was heavily intoxicated at the time.
The BBC reported that
Boris Johnson was aware of a formal complaint about Mark Pincher's inappropriate behavior while he was a Foreign Office minister from 2019-2020.
Dozens of ministers resigned in response to the controversy, leading to
Johnson's resignation as prime minister.
