Claim: Among those who resigned from their party due to the Turner Controversy were Turner himself as well as Joan Lestor, a British Labour politician.
Evidence: A series of acrimonious disputes between the 'Turnerites' and the majority of the party culminated in a party referendum and then a resolution being carried at the 1955 party conference to the effect that all members not in agreement with the Declaration of Principles be asked to resign. Turner, having survived a previous attempt to expel him, promptly did so, along with a number of other members including Joan Lestor (later to become a Labour minister) and the psychologist John Rowan. Joan Lestor, Baroness Lestor of Eccles (13 November 1931 – 27 March 1998) was a British Labour politician.
