The future of the left since 1884

Climbing the Mountain: Labour's key battlegrounds at the next election


This report identifies 150 non-Labour seats on the new boundaries which will likely make up a very high proportion of the constituencies that Labour will target at the next election.

It is based on a purely mathematical exercise that takes no account of local political factors. The group is made up of the 125 seats in England and Wales, and 25 seats in Scotland, that Labour would have come closest to winning in 2019, had that election been fought on the new boundaries. The report provides new evidence on voting intention and attitudes in these 150 key seats. This is the first time that this analysis has been undertaken.
