I think she would be a fool if she hadn't done what she has been accused off/ admitted.
All is fair in love and politics and I am sure all MPs, both sexes, use every availble trick in the book - and a lot more - to distract their opponents and disconbobulate them. That is all she did, and it seems to be successful. Now she cannot use that ploy anymore.
Having seen her on the front bench on the news, since she came into prominence, I thought that she might be using her looks and dress style to disconcert the opposition, but never having seen Basic Instincts, or bothered to read much about it, the parallels did not occur to me.
