Turner supported the invasion of Suez and was not pleased when the military action was halted. He abstained in a vote approving the policy of intervention in Egypt in December 1956, and was outraged when the Government decided to withdraw from Suez. He was one of eight Conservative MPs who decided on 13 May 1957 to resign the Conservative whip in protest. The group abstained rather than support the Government on a censure motion moved by the Opposition a few days later. Turner received a vote of confidence from the Oxford Conservative Association for his action, although the Association's agent resigned soon after, citing "internal difficulties in the association".
