The 2025 Cambridgeshire and Peterborough mayoral election took place on 1 May 2025 to elect the Mayor of Cambridgeshire and Peterborough. The Conservative candidate and former MP Paul Bristow won, gaining the seat from Labour. This was held on the same day as other local elections.
Background
The mayor of Cambridgeshire and Peterborough serves as the directly elected leader of the Cambridgeshire and Peterborough Combined Authority. The mayor has power over investment directly to the combined authority from the government of £20 million a year for 30 years from 2017. The mayor does not incorporate the Cambridgeshire Police and Crime Commissioner into the post.
In the 2021 Cambridgeshire and Peterborough mayoral election, the Labour candidate Nik Johnson was elected with 32.8% of the vote in the first round and 51.3% of the second round vote. In early 2025, Johnson announced he would not be running for a second term.
Electoral system
In 2017 and 2021, the Mayor was elected using a supplementary vote system, in which voters may express a first and second preference for candidates. The 2019–24 Conservative government abolished this system, meaning the 2025 election used first-past-the-post.
