Since 1946, many senior officials of both the Foreign Office and the Labour Party had proposed the creation of an anti-communist propaganda organ. Christopher Warner raised a formal proposal in April 1946, but Secretary of State for Foreign Affairs Ernest Bevin was reluctant to upset the pro-Soviet members of the Labour Party. Later in the summer, Bevin rejected another proposal by Ivone Kirkpatrick to set up an anti-communist propaganda unit. In 1947, Christopher Mayhew lobbied for the proposals, linking anti-communism with the concept of "Third Force", which was meant to be a progressive camp between the Soviet Union and the United States. This framing, together with anti-British Soviet propaganda attacks during the same years, led Bevin to change his position and to start discussing the details for the creation of a propaganda unit. After sending a confidential paper to the foreign secretary, Ernest Bevin, in 1947, Mayhew was summoned by Attlee to Chequers to discuss it further.
