In response to the MAUD Committee report, a nuclear weapons programme was launched. To co-ordinate the effort, a new directorate was created, with the deliberately misleading name of Tube Alloys for security purposes. Sir John Anderson, the Lord President of the Council, became the minister responsible, and Wallace Akers from ICI was appointed the director of Tube Alloys. Tube Alloys and the Manhattan Project exchanged information, but did not initially combine their efforts, ostensibly over concerns about American security. Ironically, it was the British project that had already been penetrated by atomic spies for the Soviet Union. The most significant of them at this time was John Cairncross, a member of the notorious Cambridge Five, who worked as the private secretary to Lord Hankey, a minister without portfolio in the War Cabinet. Cairncross provided the NKVD with information from the MAUD Committee.
