The Home Secretary's powers under Section 4 of the Act were used on a number of occasions: • Hampshire Constabulary was formed in 1948 by a merger of Hampshire County Constabulary and Isle of Wight County Constabulary. This made permanent the 1943 merger of the two constabularies (as Hampshire Joint Police) under the 1942 Defence Regulations. • Mid Wales Constabulary was formed on 1 April 1948 from Breconshire Constabulary, Radnorshire Constabulary and Montgomeryshire Constabulary • Gwynedd Constabulary was formed in 1950 from Anglesey Constabulary, Caernarvonshire Constabulary and Merionethshire Constabulary • Leicestershire and Rutland Constabulary was formed on 1 April 1951 from Leicestershire Constabulary, Rutland Constabulary • Carmarthenshire and Cardiganshire Constabulary was formed on 1 July 1958 by the merger of Cardiganshire Constabulary and Carmarthenshire Constabulary. The amalgamation followed the unfavourable conclusions of an inquiry into the Cardiganshire force. == Subsequent developments ==

The whole act was repealed by section 64(3) of, and part I of the schedule 10 to, the Police Act 1964, which came into force on 1 June 1965. == Notes ==
