Defence Secretary Michael Fallon has quit amid allegations of "inappropriate behaviour."
Mr Fallon is the first to resign Prime Minister Theresa May's Tory government following a wave of sexual abuse claims in Westminster over recent days.
In his resignation letter, he said: “A number of allegations have surfaced about MPs in recent days, including some about my previous conduct.
“Many of these have been false but I accept in the past I have fallen below the high standards that we require of the armed forces that I have the honour to represent.
“I have reflected on my position and I am now resigning as defence secretary.”
He apologised earlier this week for repeatedly touching journalist Julia Hartley-Brewer's knee in 2002. And, although Ms Hartley-Brewer says now that “no-one was remotely upset or distressed,” she admitted that at the time she threatened to "punch him" if he did it again.
However friends of Mr Fallon's have said that in recent months he would concede that "some of his flirtation has been inappropriate.”
