HC Deb 03 July 1979 vol 969 c510W
Dr. Edmund Marshall

asked the Secretary of State for the Home Department what periods of time have elapsed, in respect of every general review of parliamentary constituency boundaries since 1910, between the making of Orders in Council defining new constituencies and the Royal Proclamations of the first general elections held on the basis of those constituencies.

Mr. Whitelaw

From the information available to me it appears that since 1910 only two redistributions of seats following general reviews of constituencies have been effected by Orders in Council. In 1955, Orders in Council defining new constituencies were made on 5 January and 1 February and Parliament was dissolved on 6 May. Orders in Council were again made on 25 November 1970, but Parliament was not dissolved until 8 February 1974. Other redistributions were effected by legislation.
