Under the Local Government Act 1972 it had its territory enlarged and became a metropolitan borough, with West Yorkshire County Council providing county-level services.
The first election to the reconstituted city council was held in 1973, initially operating as a shadow authority before coming into its revised powers on 1 April 1974.
West Yorkshire County Council was abolished in 1986 and Leeds became a unitary authority.
Following the death, removal or resignation of an incumbent councillor between council elections, by-elections occur to elect a successor to fill the vacant council seat.
The next by-election will take place on 10 October 2024 to replace Mark Sewards in Farnley and Wortley.
