Ashford MP Damian Green has denied allegations concerning pornographic material said to have been found on a computer in his parliamentary office.

A former Scotland Yard detective has claimed that a search of the computer's internet history over a three-month period showed "thousands" of pornographic images had been viewed "extensively".

The claims dates back to 2008 when there was a Home Office leak inquiry.

Neil Lewis, who was part of that investigation, told the BBC that his analysis of the way the computer had been used left him in "no doubt whatsoever" that it was Mr Green, then an opposition immigration spokesman.

Mr Green strongly denies the allegations.

A spokesperson for Mr Green said: "It would be inappropriate for Mr Green to comment on these allegations while the Cabinet Office investigation is ongoing, however, from the outset he has been very clear that he never watched or downloaded pornography on the computers seized from his office.

"He maintains his innocence of these charges and awaits the outcome of the investigation."

A cabinet inquiry into Mr Green, the First Secretary of State, began several weeks ago after a journalist made allegations concerning inappropriate behaviour which have also been strongly denied by the MP.

That inquiry was then widened after another senior Metropolitan Police detective claimed that pornographic material had been found on a computer in the MP’s office.
