How we rate tactical-voting impact
Every constituency gets an Impact rating based on how Reform UK did there at the last election (or a later by-election), and on the latest MRP poll for the seat.
High impact - The latest MRP poll for this seat predicts Reform will win it - tactical voting may be needed to keep Reform out.
- The latest MRP poll for this seat has Reform less than 10 points behind the predicted winner - close enough that tactical voting may be needed to keep Reform out.
- Reform came second last time - tactical voting may be necessary to keep Reform out next time.
- Reform didn't win, but came within 10 points of the winner's vote share - close enough that a tactical vote may be necessary next time.
- Reform currently holds the seat but with under 50% of the vote - vulnerable to being unseated.
Medium impact - Reform didn't stand a candidate here at all last time - not the same as standing and doing badly, so it isn't Low.
- Reform either won with over 50% of the vote or came second and the winner (a non-Reform party) got over 50% of the vote outright - a landslide so this seat isn't really in play for a tactical vote to make a difference.
- Everything else - Reform is neither close behind, dominant, nor irrelevant here.
Low impact - Reform's vote share was under 10% - too far back for tactical voting to matter much here.
