Sir Michael Fallon has quit as the UK's Defence Secretary in the aftermath of being embroiled in the Westminster sex scandal.
In his resignation letter, the long-serving MP said his past behaviour had "fallen short" of what is expected in the military.
Sir Michael is the first ministerial casualty following a series of Westminster sexual harassment allegations, which have emerged in the wake of the Harvey Weinstein revelations.
Earlier this week, he apologised over an incident 15 years ago in which he made unwanted advances to the journalist Julia Hartley-Brewer, placing his hand on her knee.
HuffPost UK understands Sir Michael quit because he couldn't guarantee there would not be another story about contact with a female journalist.
