2010 boundary review
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.| Name | Boundaries 1997 – 2010 | Boundaries 2010 – present | |

| 3 | North East Cambridgeshire CC | ||

Proposed boundary changes
The Boundary Commission for England submitted their final proposals in respect of the Sixth Periodic Review of Westminster Constituencies in September 2018. Although the proposals were immediately laid before Parliament they were not brought forward by the Government for approval. Accordingly, they did not come into effect for the 2019 election which took place on 12 December 2019, and which was contested using the constituency boundaries in place since 2010.Under the terms of the Parliamentary Voting System and Constituencies Act 2011, the Sixth Review was based on reducing the total number of MPs from 650 to 600 and a strict electoral parity requirement that the electorate of all constituencies should be within a range of 5% either side of the electoral quota.
On 24 March 2020, the Minister of State for the Cabinet Office, Chloe Smith, issued a written statement to Parliament setting out the Government's thinking with regard to parliamentary boundaries. They propose to bring forward primary legislation to remove the statutory obligation to implement the 2018 Boundary Review recommendations, as well as set the framework for future boundary reviews in time for the next review which is due to begin in early 2021 and report no later than October 2023. It is proposed that the number of constituencies now remains at the current level of 650, rather than being reduced to 600, while retaining the requirement that the electorate should be no more than +/- 5% from the electoral quota.
