Reform UK would overtake in one of the two. A party's move in one cycle belongs to that campaign; this shows the size of change that has happened from here, not a forecast. Our forecast →
How this is worked out
For each past election we take every national voting-intention poll published in the fortnight either side of the same point (three weeks, or five where polls were sparse), average each pollster's polls, then average the pollsters. The UK figures are Great Britain polls against UK-wide results; Reform UK's line is UKIP in 2017 and the Brexit Party in 2019.
