The chief of the Met Police has refused to comment on claims that pornographic material was found on a computer in Ashford MP Damian Green’s office eight years ago.

Cressida Dick was quizzed on the claims by MPs on the Home Affairs select committee about the reports, which have been strenuously denied by Mr Green.

He is the subject of a cabinet inquiry into allegations of inappropriate behaviour.

Ms Dick said:“I’m not going to comment on an apparently or allegedly leaked set of information from a confidential investigation and I’m absolutely not therefore either confirming or denying what may or may not have been uncovered in that investigation.”

“What I can say is that of course if the Metropolitan Police or I myself can assist a Cabinet Office inquiry we would want to do so and we would seek to do so.”

She added: “I would be delighted if the Metropolitan Police can assist the Cabinet Office in their inquiry in any way.”

Meanwhile, the Conservative Dover MP Charlie Elphicke will not at this stage be referred to the party’s investigation panel set up to consider allegations or grievances under a new code of conduct.

Party sources say any decision will not be made until the claims made against him are considered by police.

Mr Elphicke has denied any wrong-doing and has not yet been told what the claims are. He was suspended from the party last week by the chief whip.

In another development, the Sevenoaks Labour party has started a petition calling on MP Sir Michael Fallon to stand aside as the MP for the area.

Branch secretary Seamus McCauley said: "Michael Fallon has admitted, and through his resignation acknowledged, that his conduct is inappropriate in a cabinet minister, or as a representative of Britain’s armed forces.”

“Sevenoaks Labour is therefore surprised and disappointed that Michael Fallon, and the Conservative Party, appear to feel the people of Sevenoaks are entitled to a lesser standard of conduct in their representative, and call on him to resign."
