Conservative Collapse in Their Former Heartland
The South West was the safest of safe Conservative territory for most of the twentieth century. From Cornwall to Oxfordshire, the region returned Conservative MPs generation after generation. The 2024 General Election marked a dramatic break: the Liberal Democrats swept through what had been considered safe Conservative rural seats, taking Guildford, Winchester, Horsham, South West Devon, Tiverton and Honiton and many more.
By May 2026, the Conservatives have collapsed further to 20% in the region, placing them third. Reform UK has climbed to 24% — effectively capturing the voters who feel the Conservatives have not delivered on their promises. The Lib Dems at 26% lead the region but only narrowly, and their seats are vulnerable if the Reform and Conservative vote were somehow to consolidate.
Lib Dem Rural Strength
Devon, Cornwall, Somerset and Dorset have historically had strong community-based liberal voting traditions. The Lib Dems' local council networks and long-term incumbents give them a structural advantage that national polling does not fully capture.
Reform's Coastal Surge
Coastal towns in Cornwall, Devon and Dorset have seen particularly strong Reform movement. Areas with older populations, post-fishing/post-manufacturing economies and Leave-voting majorities in 2016 are highly susceptible to Reform's message.
Green Growth
The Greens at 11% in the South West are growing in Bristol, Bath, Exeter and coastal towns. They are well-placed to take votes from Labour and potentially push for seats in Bristol and Bath at a 2029 election.

Why are the Lib Dems strong in the South West?
The South West has a long history of Liberal and Liberal Democrat support, particularly in rural Devon, Cornwall, Somerset and Dorset. The party benefits from incumbency advantage, strong local council networks and an electorate that skews older and more inclined toward centrist, community-focused politics.
Is Reform UK competitive in the South West?
Reform UK at 24% is strongly competitive in several South West constituencies, particularly coastal and post-industrial seats in Cornwall, Devon and parts of Somerset. However, the Lib Dem incumbency advantage means Reform's seat conversion rate may be lower here than in the Midlands or North.
