A leading pollster has agreed to publish more data behind its results after a row with Nigel Farage. The Reform UK leader had accused YouGov of underplaying his insurgent party’s popularity in its voting intention surveys.

The polling company – which has consistently been showing a smaller lead for Reform – asks people how they are likely to vote in their own constituency rather than which party they favour in general, which it argues is more accurate. But Mr Farage had claimed the pollster was breaking transparency rules set out by the watchdog.

In a letter to Mr Farage, Anthony Wells, YouGov’s global head of politics, said: “While data from the voting intention question without a constituency prompt is not part of our published headline figures, we are happy to include this in future published tables.”

He added: “I can assure you that our decisions on methodology will continue to be based solely and exclusively on what we think will produce the most accurate picture of British public opinion.

“We are proud of our record of accuracy at past elections both here and around the world, and not least, in correctly predicting Reform UK’s support at the last election.”

Mr Farage welcomed the move, saying: “I am pleased that YouGov have backed down and will follow British Polling Council rules.

“We can now see the full extent of how they manipulate their data to suppress Reform.”

YouGov has had Reform on an average of 24.8% in recent polls, while other pollsters have had the party close to 30%.

A YouGov spokesman said: “Our headline voting intention figures are based on how people say they will vote in their own constituencies, adjusted for likelihood to vote and don’t knows using MRP.

“We switched to asking specifically about constituencies prior to the 2024 general election, and our post-election review found this significantly increased our accuracy as it is more effective at picking up tactical voting and how people actually cast their vote.”

Nigel Farage Hails Huge Victory After Furious Row With Pollster

Nigel Farage has seized on the latest polling developments as evidence that his long-running dispute with pollsters deserves renewed attention, after previously accusing YouGov of failing to reflect the true level of support for Reform UK.

The Reform UK leader has repeatedly challenged polling methodology during 2026, particularly after a series of surveys showed his party losing ground from the much stronger position it occupied during the previous year. The latest figures, however, offer a more complicated picture: Reform remains a major force in British politics, but its position is considerably closer to its Conservative rival than it was at the height of its polling surge.

The row matters because polling has become central to the political debate surrounding Reform. Farage has frequently pointed to alternative surveys and local-election results when arguing that conventional voting-intention polls may underestimate the party’s support. YouGov, meanwhile, has defended its methodology and continued to publish detailed explanations of how its surveys are conducted.

The latest figures put Reform and the Conservatives almost level

The newest YouGov MRP, published on September 24, provides a striking snapshot of how Britain’s political landscape could look if a general election were held now.

YouGov’s central projection puts Labour on 241 seats, the Conservatives on 130 and Reform UK on 123. The model is based on fieldwork involving almost 17,000 people between August 23 and September 18.

Importantly, YouGov itself stresses that an MRP is a model rather than a forecast of an actual election result. Constituency-level estimates can change significantly as campaigns develop, candidates are selected and voters make tactical decisions.

The voting-share figures are also much closer than the seat projections might suggest. YouGov’s central estimate gives Labour 24%, Reform 22% and the Conservatives 21%.

That creates an unusual political picture. Reform is no longer operating with the commanding polling advantage seen in parts of 2025, but neither has the party disappeared from contention. Instead, the three largest parties are separated by only a few percentage points in the model’s national vote-share estimate.

For Farage, that distinction is important.

Why Farage has fought back against polling criticism

Earlier this year, Farage publicly challenged YouGov after one of its surveys placed Reform below the level suggested by several competing pollsters.

In March, YouGov’s voting-intention figures put Reform on 23%, compared with 19% for the Conservatives and Greens and 17% for Labour. Farage argued that the methodology involved adjustments that he believed were suppressing Reform’s underlying support.

The dispute became significant enough for YouGov to agree to provide more underlying information about its polling methodology. A subsequent YouGov/Sky News/Times poll in March placed Reform on 25%, with the Greens on 19%, Conservatives and Labour on 17% and the Liberal Democrats on 14%.

That episode became part of a wider argument over how Reform should be measured.

Farage has pointed towards the party’s strong performances in local and devolved elections as evidence that its electoral support can be underestimated by national polling. Critics, by contrast, have argued that local-election performance cannot automatically be translated into a future Westminster result.

Both points highlight the difficulty of interpreting polling in a rapidly changing multi-party system.

The new MRP is a mixed picture for Reform

The latest YouGov model does not provide a simple vindication for any party.

Reform’s projected 123 seats would represent a substantial increase from the five MPs it won at the 2024 general election. At the same time, it is dramatically below the level suggested by YouGov’s September 2025 MRP, when Reform was projected to be within touching distance of an overall majority.

YouGov says Reform’s challenge has increasingly become its position relative to the Conservatives rather than simply whether it can overtake Labour.

The Conservatives are projected to win 130 seats, only seven more than Reform in the central estimate.

That narrow gap is significant because the two parties compete for many of the same voters, particularly in constituencies where dissatisfaction with Labour has become an important factor.

The model also illustrates how sensitive Reform’s projected parliamentary representation could be to small changes in voting behaviour. YouGov estimates that 67% of Reform’s projected victories would come with majorities of five percentage points or less.

This means that national vote share alone cannot tell the whole story.

Other pollsters tell a broadly different story

Farage’s criticism of YouGov cannot be considered in isolation from other polling organisations.

An Ipsos survey conducted between September 10 and 15 put Labour on 27%, Reform on 23% and the Conservatives on 21%. Labour therefore held a four-point lead over Reform in that particular poll.

An earlier Opinium poll for the Observer also put Labour ahead, with Labour on 28% and Reform on 24%.

The different results demonstrate why individual polls can produce very different impressions of the political landscape.

A single survey should not normally be treated as definitive evidence of national opinion. Pollsters use different methodologies, sampling approaches and weighting systems, while the timing of fieldwork can also influence results.

This is particularly relevant for Reform because its support has moved substantially over the past year.

Reform’s polling position has changed since 2025

Sky News election analyst Professor Rob Ford recently examined Reform’s polling trajectory and found that the party’s average support across nine pollsters had fallen from the low thirties in August 2025 to the mid-twenties by August 2026.

That represented an eight-point decline over the period.

YouGov’s own September research also found that 69% of Britons held an unfavourable opinion of Farage, while 24% viewed him favourably. YouGov described the 69% figure as the highest unfavourable rating recorded by its tracker for Farage.

Those numbers provide important context for the latest polling argument.

The picture is not simply one of Reform being either “up” or “down”. The party has expanded dramatically from its 2024 parliamentary position, while simultaneously losing some of the exceptionally high levels of national polling support it recorded during 2025.

Farage can point to Clacton as another piece of evidence

Another event that Farage has used to demonstrate his political strength was the August Clacton by-election.

Farage won the contest with 22,239 votes, or 63.34%, against Count Binface’s 9,455 votes. However, the contest was unusual because the major political parties did not field candidates. Turnout was 44%.

The result therefore provides clear evidence of Farage’s ability to mobilise support in his own constituency, but it cannot by itself establish national voting intentions.

That distinction is especially important when assessing claims about polling.

A continuing battle over political measurement

The row between Farage and pollsters ultimately reflects a broader question: how should support for a relatively new and rapidly changing party be measured?

Reform’s political breakthrough has disrupted traditional assumptions about Britain’s party system. The party now competes not only with Labour but also with the Conservatives, Greens and other smaller parties for different groups of voters.

At the same time, tactical voting could become particularly important in a future general election. YouGov estimates that 37% of constituencies in its current model are decided by margins of five points or less.

For Reform, this is especially relevant because its projected gains are concentrated heavily in close contests.

That means a relatively small change in voter behaviour could alter the parliamentary picture substantially, even if national vote shares barely move.

What Farage’s “victory” really means

Farage can reasonably point to the latest figures as evidence that Reform remains a significant part of Britain’s political landscape.

But the data do not establish that his earlier criticisms of YouGov have been proven correct.

Instead, they show why the argument remains complicated. Different pollsters continue to produce different estimates, and the latest YouGov MRP places Reform close to the Conservatives while projecting both parties significantly behind Labour in seats.

The latest figures also show how quickly Britain’s political environment has changed. Reform’s projected 123 MPs would be a major increase on its 2024 representation, yet the party’s position is weaker in the current YouGov model than it was one year ago.

For Farage, therefore, the polling battle is likely to continue.

His supporters can point to Reform’s parliamentary growth, strong local-election performances and its position near the top of several national polls. Critics can point to declining averages, unfavourable ratings and the continuing gap between some Reform projections and the much stronger position the party held during 2025.

The evidence ultimately suggests a volatile and fragmented political environment rather than a settled picture.

Farage’s dispute with the pollsters may have generated another political headline, but the underlying lesson from the latest numbers is more cautious: Reform remains a major force, while the exact scale of its support remains contested and highly sensitive to methodology, tactical voting and changing public opinion.
