Reform Uk Lead In UK Polls Leaves YouGov To Publish More Data
A fresh YouGov voting intention poll shows reform uk leading on headline figures and marks the first published survey since the party publicly challenged the pollster’s methodology; YouGov has agreed to supply more of the underlying data while maintaining its established modelling approach.
Reform Uk Challenge Prompts YouGov To Release More Data
The new poll is the first since Nigel Farage and Reform UK mounted a public challenge to YouGov’s handling of voting intention questions. In response, YouGov has agreed to publish the results of its question that does not include a constituency prompt, in addition to the version with the prompt that was already provided as part of its dataset. The party has framed this change as a win for transparency, while YouGov says its overall methodology remains unchanged and it stands by its approach.
Poll Results And Recent Turnover In Numbers
The current YouGov voting-intention figures show Reform UK on 25%, up two points from the previous headline. The Greens are on 19% (no change), the Conservatives on 17% (down two points), Labour on 17% (no change) and the Liberal Democrats on 14% (no change). This particular poll was taken on Sunday 15 March and Monday 16 March, with a sample of 2, 329 respondents drawn from YouGov’s online panel.
An earlier YouGov poll taken on 9-10 March recorded a slightly lower share for Reform UK at 23%, with Conservatives and Greens both on 19%, Labour at 17% and the Liberal Democrats at 14% in that snapshot. The two polls together underline recent volatility in voting intention numbers across successive weekly surveys.
Methodology Dispute, MRP And The Two-Question Approach
YouGov’s process differs from some competitors by asking panel members two voting intention questions: one asking how they would vote if a general election were held tomorrow and another asking how they would vote if thinking specifically about their own constituency. The raw answers are then processed through a multi-level regression and post-stratification model to produce the headline voting-intention figures.
There are notable differences between pollsters in how they treat responses for Reform UK. The party has argued that the first, no-constituency question better reflects national sentiment and has questioned the impact of the second question and the MRP model on its reported share. It has cited commentary that the constituency-focused question can advantage the Liberal Democrats relative to its own performance. Separately, YouGov has previously shown lower shares for Reform UK than some other polling firms, while other companies have also recorded a decline from the party’s earlier peak.
From this week YouGov will make public both the constituency-prompted and the non-prompted question results for each poll, allowing analysts greater visibility into how the two question forms feed into the MRP output. YouGov continues to defend the twin-question approach and the use of MRP as the means to translate panel responses into a headline projection of how the country would vote.
How the newly available breakdowns will affect media and analyst interpretation of weekly headlines is not yet settled. With the pollster maintaining its methodology, the immediate change is limited to greater transparency around the component questions; the wider consequence for polling consensus and for how voting intention is forecast will depend on how researchers and political actors use the extra data in coming weeks.
