Turner was concerned also with the situation of Cyprus and in February 1958 declared that he would rejoin the Parliamentary Conservative Party if he got an undertaking that the Government would not weaken their attitude there. By June 1958, Turner and the remaining Independent Conservatives declared that they now agreed with the Government's foreign policy, and the five wrote to ask to be readmitted to the Conservative whip. After seeing Edward Heath, his application was approved.
Two years after leaving Parliament, Turner's extravagant lifestyle caught up with him. He had spent more on expenses while being a Member of Parliament than he had received in salary, which he put down to the "great deal of entertaining" he had to do in connection with the university. He had had to borrow a great deal from his bank, and his decision to stand down from Parliament was actually prompted by financial difficulties: in 1958 his affairs were placed in the hands of accountants and a committee of creditors. He was declared bankrupt, and disclosed liabilities of £6,956 compared with assets of £662. The bankruptcy hearing referred discreetly to "marital difficulties" which had also affected him; in 1966 Turner's wife, whom he had married in 1938, obtained a decree nisi of divorce against him on grounds of his desertion.
