List of general election top target seats, by party

Here is a list of the top target seats for the main political parties at the next general election.

The election is being held using new constituency boundaries, which means the results cannot be compared directly with what happened at the last general election in 2019.

In order to measure how well the parties do at the next election, and to determine which seats they need to win to form a government, a set of notional results for the 2019 election has been calculated to show what would have happened if that contest had taken place using the new boundaries.

These notional results have been compiled by Professors Colin Rallings and Michael Thrasher of the University of and Sky News.
