"Mark Garnier is to face an investigation into whether he broke ministerial rules after he admitted asking his secretary to buy sex toys.The international trade minister also confirmed calling her "sugar tits,"according to the Mail on Sunday but he said it did not amount to harassment.
The Cabinet Office will look at whether the Ministerial Code of Conduct has been breached,as he did not respond to the comments.
Mr Garnier's former secretary,Caroline Edmondson,told the Mail on Sunday he had given her money to buy two vibrators at a Soho sex shop.
Ms Edmondson,who has since left to work for another MP,was quoted as saying that on another occasion in a bar, in front of witnesses, he told her: "You are going nowhere,sugar tits."
The Mail reported that Mr Garnier had admitted the claims,saying: "I'm not going to deny it,because I'm not going to be dishonest.I'm going to have to take it on the chin."
Mr Garnier conceded that his actions could look like ackward behaviour" in the current climate,but added: "It absolutely does not constitute harassment."
News had it that Andrew Marr on Sunday, Health Secretary Andrew Hunt said recent newspaper reports about inappropriate behaviour by MPs and ministers were "totally unacceptable if true".
Asked about the working culture at Westminster,he said:"Things have got better in recent years but there is still some way to go.
"There are mums and dads who have daughters who are politics students hoping to get a job in Westminster,and they must be able to be confident that if they get that job,their daughter will not be subject to some of these behaviours that we have been seeing." Shadow Home Secretary Dianne Abbott told the Andrew Marr show the culture for women in Parliament had improved since she was elected in 1987,but said there was "still a long way to go".She also criticised Conservative Environment Secretary Michael Gove, who was forced to apologize on Saturday after he likened being interviewed by BBC presenter John Humphrys to "going into Harvey Weinstein's bedroom".
"I heard it and I didn't think it was funny - particularly in Parliament,making sexual harassment a joke is one of the reasons it's not being dealt with,"she said.
"You've got to realise that it's undermining and demeaning for women and undermines and demeans the institution."
Ms Abbott said Labour had set up a new process for dealing with complaints of sexual harassment,but she stressed that it was an issue for all parties to deal with.
Meanwhile,former Welsh Secretary Stephen Crabb was reported by the Sunday telegraph to have admitted sending "explicit" messages to a 19-year-old woman after a job interview at Westminster in 2013.
The married MP,who admitted meeting the woman "a few times,"was quoted by the paper as saying he had been "foolish" but that there had been no sexual contact.
"I accept any kind of sexual chatter like this is totally wrong and I am sorry for my actions," the MP for Preseli Pembrokeshire said.
Mr Crabb resigned last year as work and pensions secretary following reports of a similar incident.
