The article’s core factual spine—YouGov Westminster voting intention figures (Reform 23, Green 21, Labour 16, Conservative 16, Lib Dem 14) and the timing/sample window (1–2 March; n≈2,073), plus the Green by-election win in Gorton & Denton on 26 February 2026 and its consequence of taking the Greens to five MPs—can be corroborated by multiple reputable and/or primary sources.

The article’s core factual spine—YouGov Westminster voting intention figures (Reform 23, Green 21, Labour 16, Conservative 16, Lib Dem 14) and the timing/sample window (1–2 March; n≈2,073), plus the Green by-election win in Gorton & Denton on 26 February 2026 and its consequence of taking the Greens to five MPs—can be corroborated by multiple reputable and/or primary sources. However, several secondary detail claims (e.g., whether this is definitively the first time in YouGov’s regular series the Greens placed second; demographic/crosstab percentages; Darren Jones quotation context; prior Reform “peaks above 29%”; and the exact Ipsos ‘as high as 30%’ framing) are not all confirmable from primary documentation within the available open sources, and are therefore marked Unverified rather than False.

Confidence
Medium — High confidence in the by-election facts due to an official UK Parliament source and convergent reputable reporting. Medium confidence in the poll toplines because several reputable outlets describe the same figures, but the pollster’s original tables/time-series documentation for this exact survey was not directly verified in the retrieved open sources. Lower confidence on the article’s more granular crosstabs and ‘first time/highest ever/record low’ superlatives, which require direct YouGov documentation or equivalent primary evidence.
