Dad's revolutionary army

When Britain's back was against the wall in the dark days of July 1940 thousands of British civilians were being trained in the arts of garrotting, making bombs and killing quietly with knives. In contrast to the classic BBC TV situation comedy "Dad's Army" -- the escapades and mishaps among members of the Home Guard -- the targets of this early 'dad's army' weren't German but British. This private army of socialist revolutionaries, based at the end of the London Underground's Piccadilly Line, feared that the British government would roll over like Vichy France. If it did it faced a civil war with this new British Resistance. The early Home Guard believed that Foreign Secretary Lord Halifax was leading the call to give in. Lord Foot, who then backed a guerrilla war, had plans for Halifax if he did. The 93-year-old former Labour leader told this programme: "I'd have killed him." "Document" traces members of this left wing militia, discovers government pressure to quash BBC of them and MI5 plots to infiltrate 'dad's revolutionary army'.
