Seats affected by projected boundary changes

London

Seats within the quota

Under quota seats

Seats exceeding the quota

All constituency colours are based

on 2015 election result

Constituency boundaries are drawn based on the number of parliamentary electors (as of 1 Dec 2015) living in each area. They must fall within the quota range of 71,031-78,507* people per constituency

Many above quota will simply lose part of the constituency, although in some parts of the country they could be broken up because of a knock-on effect as seats around them change.

Those under quota will have to be changed to fall within the quotas, and are expected to be the most vulnerable.

Constituency seats that are within quota are least likely to be affected as the Boundary Commission aims to minimise the amount of change.
