The 2023 Brentwood Borough Council election took place on 4 May 2023 to elect members of Brentwood Borough Council in Essex, England.[1] This was on the same day as other local elections in England.
Prior to the election the Conservatives had a majority on the council. The leader of the council before the election, Chris Hossack, chose not to stand for re-election.[2]
Following the election the council went under no overall control. A Liberal Democrat and Labour coalition formed to take control of the council, with Liberal Democrat leader Barry Aspinell being confirmed as the new leader of the council at the subsequent annual meeting on 17 May 2023. Will Russell took over as the new leader of the Conservative group in opposition.[3]
The Statement of Persons Nominated, which details the candidates standing in each ward, was released by Brentwood Borough Council following the close of nomination on 5 April 2023.[4] The results of the election were announced on 5 May 2023.[5]
