Merthyr Tydfil County Borough Council
Merthyr Tydfil County Borough Council is the governing body for Merthyr Tydfil County Borough, one of the Principal Areas of Wales.
Background
Elections take place every four years. The last election was 4 May 2017. This election saw a big swing, with Independent councillors winning majority control from the Labour Party, in what was previously a Labour stronghold. The final result was delayed because of the death of a candidate in the Cyfarthfa ward, where the election took place on 8 June to choose the final three councillors. Labour council leader Brendan Toomey lost his seat at the election.At the May 2004 elections the Labour group were challenged by a new party, People Before Politics, who won nine of the 33 seats across four wards. PBP's numbers reduced to three and the party was disbanded before the next election.
