Citrine declined Churchill's offer to serve in his all-Party war-time coalition government. He did accept the position of Privy Councillor and this gave him total access to the Prime Minister and considerable influence with all Ministers on behalf of the TUC throughout the war. Together with Bevin who became Minister of Labour and National Service, they mobilised and directed the organised working classes' enthusiastic productive effort for victory. Citrine also acted as an envoy for the Prime Minister with the U.S and Soviet trade unions. This major contribution to the war effort immensely strengthened the position of the Labour ministers in Churchill's government of 1940 to 1945 which greatly assisted Labour's election as a majority government in 1945. That government's radical programme had been shaped on the National Joint Council of the 1930s. With this new prestige and standing, the trade unions came to be regarded as 'an estate of the realm', by all parties.
