The parish of Merthyr Tydfil was governed by a local board from 1850 until 1894, when it was replaced by an urban district council. The urban district was incorporated as a borough in 1905, creating the first Merthyr Tydfil Borough Council. In 1908 it became a county borough, making it independent from Glamorgan County Council. It retained county borough status until 1974, when there were significant changes to local government under the Local Government Act 1972. From 1974 until 1996, Merthyr Tydfil Borough Council was a lower-tier district council, with Mid Glamorgan County Council providing county-level services in the area. Since the abolition of Mid Glamorgan County Council in 1996, Merthyr Tydfil has again been a county borough.[4][5]
Political control
The council has been under no overall control since the 2022 election, with the independents and Labour each having 15 councillors. The independents managed to form the council's administration on the mayor's casting vote.[6] Following a number of changes of allegiance and a by-election, the independent administration was replaced in September 2024 with a minority Labour administration.[2]
The first election to the council following the Local Government Act 1972 was held in 1973, initially operating as a shadow authority before coming into its revised powers on 1 April 1974. Political control of the council since 1974 has been held by the following parties:[7]
Twelve of the independent councillors sit together as the 'Independent Group', two form the 'Pant Community Independents' and the other two are not aligned to a group. The next election is due in 2027.[14]
