Elections to Basingstoke and Deane Borough Council took place on 6 May 2021 as part of the 2021 United Kingdom local elections.[1] They took place at the same time as the elections for Hampshire County Council and the Hampshire Police and Crime Commissioner.[2]
Whilst an election for the County Council had already been planned, District Council Elections were delayed due to the ongoing COVID-19 pandemic, meaning that they are due to be held at the same time as the Hampshire County Council Elections.[3]
The Conservatives won 12 seats at the previous election, with Labour and the Liberal Democrats winning 4 each. Subsequent to the 2019 election, initially nine former Labour Councillors joined with existing independent councillors to form the Basingstoke & Deane Independent Group,[4] which by May 2021 had 10 borough councillors, sitting as part of The Independent Forum alongside an independent.[5] Alongside the Basingstoke & Deane Independents, the newly founded county-wide Hampshire Independents are also standing several candidates.
The Statement of persons nominated was revealed on Friday 9 April 2021.[6]
The Conservatives won 33 seats across the district, whilst Labour won 10, the Liberal Democrats and Basingstoke & Deane Independents won 5 seats each, and a non-affiliated independent won a seat.[7]
