The Conservatives would have won a majority if June’s snap general election had taken place under proposed new constituency boundaries, experts estimate.
Professors Colin Rallings and Michael Thrasher, of the University of Plymouth, estimate the changes would have given Theresa May about 308 MPs, enough for an overall majority of 16.
The estimate has fuelled criticism from opposition parties that the proposed changes will work in Tories’ favour in the next election planned for 2022.
The changes announced by the Boundary Commissions for England, Scotland and Wales would reduce the number of MPs in the House of Commons from 650 to 600.
You can use the interactive map to view the plans and compare them with your existing constituency boundaries.
For example, the map above shows Jeremy Corbyn’s existing constituency of Islington North, which would be abolished if the changes go ahead.
The constituency would be divided between three new constituencies also covering Stoke Newington, Camden and Islington.
The map above shows Boris Johnson’s Uxbridge and South Ruislip seat is also slated to be scrapped with large parts moved to a new constituency of Hillingdon and Uxbridge.
