The 2017 Welsh local elections were held on 4 May 2017 to elect members of all 22 local authorities in Wales. This included the Isle of Anglesey, which was previously up for election in 2013 due to having its elections delayed for a year. Community council elections also took place on the same day. These local elections were held as part of the 2017 local elections in the United Kingdom. Apart from Anglesey, the last elections were held in 2012. Normally these elections take place every four years, but the 2017 elections were postponed for a year in order to avoid clashing with the 2016 Welsh Assembly election, which itself had been postponed by a year to avoid clashing with the 2015 general election.
Welsh Labour incurred a net loss of 112 council seats, losing control of the Blaenau Gwent, Merthyr Tydfil and Bridgend councils. Labour did, however, retain control of Cardiff, Swansea, Newport, and five other councils. The Welsh nationalist party Plaid Cymru saw a net gain of 38 seats and retained control of Gwynedd Council, while also falling just short of controlling Carmarthenshire County Council. The Welsh Conservatives saw a net gain of 79 seats, and gained control of one council, Monmouthshire. The Conservatives also became the largest party in Vale of Glamorgan and Denbighshire. In ten of the 22 councils, no party had overall control of the council.
Background
In the last local elections in Wales in 2012 (including a delayed election for the Isle of Anglesey County Council in 2013), 1,265 councillors were elected across Wales. The Labour Party won 580, independents won 307, Plaid Cymru won 170, the Conservatives won 105 and the Liberal Democrats won 73. Other parties, including the UK Independence Party, won 30 seats. Ahead of the 2017 elections, Labour were defending 536 seats and control of ten of the twenty-two Welsh local authorities. Plaid Cymru was defending 177 seats, and the Conservatives was defending 103 seats. The Liberal Democrats were defending 75 seats, having "made a net gain of three council seats as a result of by-elections and defections" since 2012. The Wales Green Party was defending a single seat.
Labour had suffered defections among its Welsh councilors prior to the 2017 elections. In September 2014, ten Labour councillors on the Wrexham County Borough Council left the Labour Party and quit the Labour council group. In August 2016, the councilor for Splott, Cardiff left Labour. In November 2016, Labour lost two of its Cardiff councillors in two days, with the Llandaff North councillor resigning from the council because of a "culture of bullying" and the Adamsdown councillor leaving the Labour group to sit as an independent after he was not re-selected to run in 2017. In 2015, control of Carmarthenshire Council was lost to a Plaid Cymru led coalition, whilst in 2016 the party also lost control of Maesteg Town Council for the first time since it was created in 1974 after the de-selection of several Bridgend Labour county councillors.
A total of 1,159 seats were up for election in the 2017 Welsh local elections. Labour fielded 910 candidates, the Conservatives 621 candidates, Plaid Cymru 549 candidates, the Liberal Democrats 280 candidates, UKIP 80 candidates, and the Greens 78 candidates. Additionally, more than 870 people ran as independent or candidates for other parties. 10.4% of wards were uncontested with almost a hundred candidates running unopposed. In one ward, Yscir in Powys, no candidate filed to run. The election for that ward was deferred until the 21 June 2017, when it was won by the Conservatives. Elections in the wards in Cyfarthfa, Merthyr Tydfil and Llandyfriog, Ceredigion were postponed following the deaths of local candidates.
