Where the parties stand
A sample-weighted trend across every published national poll, shown with the uncertainty attached. A single poll is a noisy measurement — the band matters more than the line.
Primary vote trend
134 polls from 13 polling organisations, fieldwork between 18 May 2025 and 16 July 2026.
Known limitations of this dataset
7 of 134 records carry a caveat. We publish these rather than quietly dropping or patching them, because a silently “clean” dataset is the easiest kind to mislead with.
