Defence Regulation 18B was a sub-section of the Emergency Powers (Defence) Act 1939 passed by the Houses of Parliament prior to the outbreak of the Second World War. 18B allowed the government to intern individuals suspected of being Nazi sympathisers, suspending their right to habeas corpus. Sir Oswald Mosley and his wife Lady Diana Mosley, as well as a number of their acolytes, were interned in London and later on the Isle of Man under 18B. This volume contains Home Office records relating to their imprisonment.
