in early 1939, when war seemed imminent, he made contact with Oswald Mosley in an attempt to co-ordinate activity against the war. Despite his earlier anti-war agitation, in Winston Churchill's wartime government, he was appointed Minister of Transport in October 1940 and joined the Privy Council, becoming Minister of Aircraft Production in May 1941. As the Minister of Transport he proposed the use of Airgraphs to reduce the weight and bulk of mails travelling between troops fighting in the Middle East and their families in the UK. He was forced to resign in 1942 for expressing the hope that Germany and the Soviet Union, then engaged in the Battle of Stalingrad, would destroy each other.

He was appointed a Knight Grand Cross of the Order of the British Empire in 1953.
