 Wolseley had begun aero engine development in 1929 but when Wolseley Motors became a subsidiary of Morris Motors Limited on 1 July 1935 it had been decided to keep aero engine development quite separate.So this business remained Lord Nuffield's personal property and did not become part of the Morris Motors group.In 1935 at the personal request of the Prime Minister, Stanley Baldwin, Lord Nuffield took on the job of bringing up-to-date the mechanization of the Army and the ground section of the Air Force.
