Pym was a leading member of the Wets, Tories opposed to Thatcherism. During the 1983 general election campaign he said on the BBC's Question Time that "Landslides don't on the whole produce successful governments". This was publicly repudiated by Margaret Thatcher and he was sacked after the election. Shortly afterwards, he launched a pressure group called Conservative Centre Forward to argue for more centrist, One Nation policies. But with Thatcher at the height of her powers, it was unsuccessful. He stood down at the 1987 election and was created a life peer as Baron Pym, of Sandy in the County of Bedfordshire on 9 October 1987. He was the author of The Politics of Consent published in 1984 after he left office. The book is a guide to the Wets' opposition to Margaret Thatcher, both to her leadership style and policies.
