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. 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. 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. == Eligibility to vote ==
