Is Keith Vaz a psychopath?

What’s wrong with you?’ That was the question an American broadcaster asked Anthony Weiner when his New York City mayoral campaign went up in flames in 2013. Weiner, the subject of a feature-length documentary released earlier this year, had just become embroiled in a second sex scandal, the first having derailed his political career in 2011. The extraordinary thing about the second scandal is that his efforts to rehabilitate himself as a public figure, helped by his wife’s decision to stand by him, seemed to be working. He was topping the polls when the scandal broke, which demands the question: ‘Why risk it all again?’ You’d think his experience would have taught him a lesson, but apparently not. And since the documentary was made his aberrant behaviour has continued. Last month he was caught out for a third time and his wife, a prominent aide to Hillary Clinton, finally ditched him.
