Eric Roberts (spy)
Eric Arthur Roberts (18 June 1907 - 17 or 18 December 1972) was an MI5 agent during the Second World War under the alias Jack King. By posing as a Gestapo agent, and infiltrating fascist groups in the UK, Roberts was able to prevent secret information finding its way to Germany. Roberts continued to work for the security services after the war, notably in Vienna, but it was a time of great anxiety in the services due to the suspicions surrounding double agents such as the Cambridge Five. Roberts never felt completely accepted by MI5 due to his different social background, and moving to a less active desk role did not suit him so well as his wartime role.
Early life
Roberts was born in Wivelsfield in June 1907, the son of Percival Arthur Garfield Roberts and his wife Maud (née Green). At the time of the 1911 census, the family was living in Penzance, where his father worked for the Western Union Cable Company. Eric eventually settled with his family in Epsom.
He became a bank clerk in the Euston Road branch of the Westminster Bank in London. He spoke fluent Spanish and some German following holidays there in 1932 and 1934. He married Alice Lilian Audrey Sprague (born 1900 Droylesden, Lancashire), the daughter of William Sprague, a railway civil engineer, and his wife Margaret, in spring 1934.
