Two nights before the Conservative Party leadership election in November 1990, he visited Prime Minister Margaret Thatcher at 10 Downing Street. He advised her that her time as Prime Minister was drawing to a close and that she should back John Major to take over the role. His reason for doing so was that he felt that her Conservative colleagues would not tell her straight that she could not win a leadership contest. Following this meeting, he was smuggled out of Downing Street's back door. Two days later Margaret Thatcher supported John Major for the post, and Major went on to become Prime Minister.
