Less predictably, except to those who knew his earlier career, he took the chair in 1987 of the newly created all-party anti-apartheid group, to counter the activities of the pro-South African committee led by his Conservative colleague John Carlisle. He was critical of Margaret Thatcher for appearing to condemn sanctions more than she condemned apartheid and refused to criticise the African National Congress for resorting to violence. He backed the attempt of the Eminent Persons Group to end apartheid and subsequently urged that sanctions should be strengthened, arguing that the South Africans had no intention of changing and that they could only be induced to do so by pressure, and backed their continuance in 1990.
