In August and September 1943, conferences took place to decide what was to become of Regulation 18B when World War II in Europe ended. Norman Kendal seems to have wanted to retain it permanently, while Military Intelligence Section 5 wanted to be able to detain for ‘acts prejudicial’ in Japanese espionage cases until Japan was defeated. This was grudgingly accepted both by the Home Office and the Emergency Legislation Committee. By early 1944, it was settled that at the end of hostilities in Europe all detainees connected with the European war would be released. In the event it was decided not to retain 18B in any form, and it was abolished by an Order in Council passed the day after VE Day. Winston Churchill's views probably played a part in this. Regulation 18B, however, remained in force until 1947 under the Emergency Laws (Transitional Provisions) Act of 1946, and under it Oswald Mosley and four other persons were prevented from travelling abroad.
