The ceremonial county of Cambridgeshire (which includes the area of the Peterborough unitary authority) is divided into seven parliamentary constituencies. There are two borough constituencies and five county constituencies, which each elect one Member of Parliament to represent it in the Parliament of the United Kingdom. Constituencies 2010 boundary changes The 2007 report of the Boundary Commission for England retained the same seven constituencies that had existed since the 1997 election, with minor boundary changes to align with current local government wards and to better equalise the electorates. These changes, which were implemented at the 2010 general election, included the transfer back of Thorney and Eye from North East Cambridgeshire to Peterborough, the return of the Cambridge ward of Trumpington from South Cambridgeshire to the Cambridge constituency, and small transfers of rural wards from North West Cambridgeshire to Huntingdon, and from South East Cambridgeshire to South Cambridgeshire. Proposed boundary changes See 2023 Periodic Review of Westminster constituencies for further details. Following the abandonment of the Sixth Periodic Review (the 2018 review), the Boundary Commission for England formally launched the 2023 Review on 5 January 2021. Initial proposals were published on 8 June 2021 and, following two periods of public consultation, revised proposals were published on 8 November 2022. Final proposals will be published by 1 July 2023. The commission has proposed that the number of seats in Cambridgeshire be increased from 7 to 8, with the creation of the constituency of St Neots and Mid Cambridgeshire, resulting in significant changes to Huntingdon, North West Cambridgeshire, South Cambridgeshire and South East Cambridgeshire (to be renamed East Cambridgeshire).
