When newsprint rationing ended, Bishop became Chairman of Morphy Richards, the consumer electrical company in 1957. He supported the Public Bodies (Admission of the Press to Meetings) Bill promoted by Margaret Thatcher in 1960, a Bill prompted by the decision of some Labour-controlled councils to refuse admission to the press where the newspapers involved were in the middle of an industrial dispute. Morphy Richards were taken over by EMI in 1960, a move opposed by Bishop and which led to his resignation that December.
