Boris Johnson is being pressured to disclose what he knew about the inappropriate behavior of Chris Pincher, Chris Pincher's deputy chief whip.
Anneliese Dodds, Labour chairwoman, wrote to the PM to inquire about the details of what No. 10 knew about the claims.
She said that only Boris Johnson could have seen this man's record and concluded that he deserved a promotion.
Minister Therese coffey stated that the PM wasn't aware of any "specific allegations".
Following allegations that Pincher had groped two men on Thursday, Mr Pincher quit as deputy chief whip, telling the PM that he "drank too much". He was then suspended as a Conservative MP.
Six new allegations of inappropriate behavior against Mr Pincher date back many years. He has denied these claims.
Last week, his resignation was his second departure from the whips office.
After Alex Story, Conservative candidate for 2017, accused him of making an inappropriate advance in 2017, he resigned.
Ms. Dodds stated that the PM was "happy to sweep sex misconduct under the rug in order to save himself."
She also questioned the reason why the Tory whip wasn't suspended on Friday, two days after the alleged incident at London’s Carlton Club.
Ms Coffey, Work and Pensions Secretary, stated on Sunday that the prime minister wasn't aware of any specific allegations against Mr Pincher at the time he was appointed to whips' office in Feb.
She stated that she had not spoken directly to the prime minister and had received assurances from the No 10 Press Office.
She told Sky News that Mr Pincher's February appointment had been vetted "like normal".
No 10 has not denied Dominic Cummings' claim that Mr Johnson's ex-chief aide claimed that Johnson referred to Dominic Cummings as "Pincher by Name, Pincher by Nature" before appointing him.
Johnson faces questions from his party members about his handling of the allegations.
Some suggestions suggest that there could be a confidence vote for PM during the forthcoming elections for the executive of 1922 Committee's backbench group. This would go against party rules.
This change would allow for a second confidence vote if 90 Tory MPs (25%) send letters to the 1922 leadership.
Mr Pincher is still an independent MP for Tamworth, Staffordshire.
