This is the second of our episodes about the Cambridge Five!

This week – Guy Burgess. Where the others were highly self-controlled and shunned public scrutiny, he was wildly flamboyant, openly homosexual and often embroiled in scandal because of his drunken behaviour. He had the ability to charm anyone he sought out, including Churchill, and attracted an astonishing array of contacts, as well as lovers, as he flitted between MI5, MI6, the BBC and the FO. At one point he was simultaneously running agents for both British and Soviet intelligence. Between 1941 and 1945 he passed more than 4,600 documents to Moscow.
