The UK Parliament has decided to reduce the number of constituencies, and therefore MPs, from 650 to 600. In England, the number of constituencies will reduce from 533 to 501.
The Boundary Commission for England is the independent and impartial body that is considering where the boundaries of the new constituencies should be. They must report to Parliament in September 2018. In doing so, they have to ensure that every new constituency has roughly the same number of electors: no fewer than 71,031 and no more than 78,507. While proposing a set of boundaries which are fairer and more equal, the Commission will also try to reflect geographic factors and local ties. The Commission will also look at the boundaries of existing constituencies and local government patterns in redrawing the map of parliamentary constituency boundaries across England.
No changes to the existing boundaries of the Epsom & Ewell Constituency are proposed in the initial report published by the Boundary Commission as part of it's consultation process.
The Commission is promoting use of a specifically-designed consultation website for this review as the primary tool for displaying its proposals, and receiving comments on them. This is available here. The public consultation period runs until 5 December 2016. Also, as requested by the Commission, the proposals and maps for all nine English regions are available at the Town Hall reception for the public to view if they so wish.
