Six new allegations of inappropriate behavior by Chris Pincher, former Conservative deputy chief whip, have surfaced just days after he was expelled from the party over groping two men.
These allegations go back over a decade.
Mr Pincher, who represents Tamworth in Staffordshire, said he is looking for professional medical help and does not intend to resign as MP.
Although he did not reply to the BBC, he denied the allegations to the newspapers.
Three cases in which Mr Pincher allegedly made unwelcome advances to male MPs are reported by the Independent, Mail on Sunday, and Sunday Times. These include alleged advances in a bar in Parliament and in his own parliamentary offices.
There were never any complaints.
According to reports, one of the MPs reached Downing Street in February to share details about what had happened and expressed concern that Mr Pincher might become a party whip responsible for disciplining and welfareing other MPs.
Whips are MPs responsible for party discipline and have the responsibility of ensuring that all MPs vote in line with party lines in Parliament.
Downing Street claims that Boris Johnson appointed Mr Pincher deputy chief whip, despite not being aware of any specific allegations.
After allegedly groping two men at London's Carlton Club, the Conservative Party members club, Mr Pincher was forced to resign as Tory deputy chief whip.
No 10 suggested at first that the prime minister had closed the matter after he resigned as deputy chief whip.
After being reported to Parliament's behavior watchdog, Mr Pincher was removed as a Conservative MP and will now sit as an independent.
Mr Pincher claimed that he had drunk "far too much" Wednesday night and "embarrassed myself and others. I'm truly sorry for the distress I caused."
"The stress of the past few days, on top of those of the previous several months, have forced me to accept that professional medical support will be of benefit to me," Mr Pincher stated in a statement.
"I am currently seeking that right now and I hope to be in a position to return to my constituency duties soon."
Although No 10 was criticised for not taking action quickly, a source within the government said that they took swift action after receiving the complaint.
Independent investigators review complaints against MPs and make recommendations about further action. The MPs would vote on whether to suspend or expel the MP.
In 2017, Mr Pincher resigned from the whips' offices after he was accused, among other things, of making a rash pass at Alex Story, an ex-Olympic rower and Conservative activist.
After an investigation by the party he was cleared of any violation of its code.
