About this tactical voting guide

What this is

This site helps you vote tactically against Reform UK at the next general election. For every constituency in Great Britain it shows how Reform did at the last election, what the latest polls predict, and which party is best placed to beat them there.

Each seat also gets an impact rating (High, Medium or Low) showing how much a tactical vote is likely to matter where you live.

How we decide who's best placed to beat Reform

Each constituency's recommendation starts from the most recent real result: the 2024 general election, or a later by-election where there's been one. We take the party whose candidate got the most votes apart from Reform UK, whether Reform won the seat, came second or finished further back.

We then check the latest MRP poll for the seat (a large poll modelled down to each constituency). If the poll's predicted winner is a different party from the last result, we recommend the poll's party instead, and the page says so. Where the poll predicts Reform will win, we compare against the party it puts second. If that place goes to independents or the smaller parties the poll groups together as "others", we keep the last-result recommendation, because the poll can't say which candidate that would be.

Occasionally we set a recommendation by hand, for example where the numbers point to a party that doesn't make sense as a tactical choice. When we do, the constituency's page shows a note explaining why.

This is a consistent rule, not a guarantee. MRP polls are estimates with margins of error, and things change before an election: candidates stand down and local issues shift. Treat it as the best guide available, and check the figures on your constituency's page.

Where the data comes from

Election results come straight from Wikipedia's results tables. No vote numbers are typed in by hand. Each constituency page links to the exact Wikipedia page its result came from and shows when it was retrieved, so you can check it yourself.

Predictions come from YouGov's MRP polls, which estimate each party's share of the vote in every constituency. We publish YouGov's figures as they release them, without adjusting them. Each prediction shows which poll it comes from, its date and a link to the source, and older polls stay available so you can see how things have moved.

Constituency maps are the boundary maps used on Wikipedia, from Wikimedia Commons. Each map is credited to its creator under its licence, shown beneath it. Most are based on Ordnance Survey boundary data.

Postcode search uses the Office for National Statistics' official postcode-to-constituency lookup.

Sometimes the figures alone would mislead. For example, a by-election that the main parties chose not to contest can make an unlikely party look best placed. In those cases we set the recommendation or impact rating by hand, and the constituency's page shows a note explaining why.

Coverage

All Great Britain constituencies are covered. Northern Ireland isn't included, since Reform UK doesn't contest seats there.
