Local Government Act 1972
Elections were held to the new authorities on three different Thursdays in 1973.  Each new county and district was divided into electoral divisions. For county councils, each electoral division elected one member; for metropolitan district councils, each ward elected three members; and wards in non-metropolitan districts could elect a varying number of members.  There was not sufficient time to conduct a full warding arrangement so a temporary system was used: in some county councils electoral divisions elected multiple councillors.
