Ms Griffiths, 49, called the party "institutionally sexist" and said of Labour men: "They treat me and others like a girl who should not be playing big boys' games." A self-confident politician, she compares herself-to the Iron Lady on her website, declaring: "I am the first woman MP for Reading. That can never be taken away - just as it can never be taken away from Margaret Thatcher that she was the first woman prime minister."
