Edited sentence: Antony Flew was a supporter of the British Labour party, who later became a supporter of classical liberalism (a political philosophy based on private property and individual freedom).I do not believe that he has ever described himself as a "conservative" although he voted for candidates of the British Conservative party in many general elections and was a strong supporter of Margaret Thatcher (leader of the British Conservative party from 1975 to 1990), therefore it would not be wildly unfair to describe him as a "conservative"
