  In 1958 Ayer took the opportunity to return to Oxford as Wykeham Professor of Logic. He later said that this decision was made in order to combat the growing influence of Austin, who had made a point of attacking Ayer’s views on perception. Austin was, however, soon to die, making Ayer’s ‘sacrifice’ of his life in London somewhat pointless. Not that it was completely sacrificed; he bi-located, spending long weekends in London with his second wife, Dee Wells, and at most three nights in New College during the week. He continued to travel widely: China, Russia, India, and Pakistan were added to the itinerary. He also continued his political activity, continuing to support the Labour Party, campaigning against British involvement in Vietnam, and being at one time Vice-President of the Society for the Reform of the Abortion Law, Chairman of the Campaign Against Racial Discrimination in Sport, and President of the Homosexual Law Reform Society. His support for the decriminalization of homosexual behavior, he once quipped, could not be thought by anyone acquainted with him to involve a vested interest. Ayer’s support for the Labour Party came to an end with the formation of the Social Democratic Party in 1981. His support for the SDP was a protest at the leftward trend of the Labour Party, and particularly its anti-Europeanism.
