 Mosley was interrogated for 16 hours by Lord Birkett but never formally charged with a crime, and was instead interned under Defence Regulation 18B.The same fate met the other most active fascists in Britain, resulting in the BUF's practical removal at an organized level from the United Kingdom's political stage.Mosley's wife, Diana, was also interned in June, shortly after the birth of their son (Max Mosley); the Mosleys lived together for most of the war in a house in the grounds of Holloway prison.
