A WOMAN has come forward to reveal a THIRD serious sex pest allegation about shamed Sir Michael Fallon.

The unnamed woman reported to No10 on Tuesday that the ex-Defence Secretary had groped her.

The allegation of inappropriate physical contact was not made by an MP.

It was taken very seriously by Theresa May and her chief of staff, Gavin Barwell, as highly credible.

The complaint followed fellow Cabinet minister Andrea Leadsom’s whistle blowing claims about Sir Michael’s lewd comments to her, and how he once repeatedly put his hand on radio host Julia Hartley Brewer’s knee.

Like Ms Leadsom, the woman was also furious that Downing Street had appeared to clear the defence supremo when the Ms Hartley Brewer incident of 15 years ago emerged.
