Key takeaway

The Greens lead Labour nationally for the first time; Reform's lead is the largest it has recorded.

YouGov's Westminster voting intention poll on 19-20 April fieldwork put Reform UK on 27%, the Green Party on 17%, the Conservatives on 17%, Labour on 16%, the Liberal Democrats on 14%, and Restore Britain on 3% ¹. The sample size was 2,472. It is the first national Westminster poll in which The Greens lead Labour outright, and Reform's largest-ever national polling lead. Labour finishes fifth on the central estimate.

The Greens' rise tracks the same urban-Labour decay registered by the Salford Barton and Winton by-election the same week, where the party finished third on 18.7%. Reform's 27% sits inside the polling band that has held since February . The novelty in the sample is the Labour floor, which has now broken below The Greens. Whether the result is a single-poll outlier or a sustained reordering of the centre-left vote is the question every party manager will be reading the next YouGov for. The local elections on 7 May supply the first ballot test.

Deep Analysis

In plain English

Westminster voting intention polls ask a sample of people which party they would vote for in a UK general election. YouGov's poll from 19-20 April 2026 , the most recent before the 7 May local elections , showed the Green Party (17%) ahead of Labour (16%) for the first time in any national poll. Reform UK led on 27%. The Conservatives tied the Greens at 17%. Labour finished fifth on 16%, behind four other parties. In the UK's Westminster voting system (first-past-the-post), a party's national vote share does not directly determine how many MPs it wins. Labour's vote is geographically concentrated in cities, meaning it wins more seats per percentage point than the Greens. The Greens won four Westminster seats in the 2024 general election with fewer total votes than this poll suggests they now hold nationally. The party's growth under Zack Polanski, who took over as leader in September 2025, has been driven by anti-government voters, particularly under-40s in urban areas, who are deserting Labour over Gaza, housing, and cost of living.

What could happen next?

Consequence
Labour now faces three-front vote loss: Reform on its right flank in traditional northern seats, Greens on its left in urban seats, and Your Party targeting Muslim-majority wards.

This Event

Greens overtake Labour in YouGov national VI

Two polling firsts in the same sample, days from the local elections that will test both the Reform ceiling and the Labour floor on actual ballots.

Different Perspectives

Welsh Government (Plaid Cymru under Rhun ap Iorwerth)

Plaid's Cardiff minority government relies on Green confidence-and-supply with no written agreement, the same arrangement that collapsed in Scotland in 2023. Green Westminster polling fell from 17% to 15% in two weeks as Greens took governing responsibility; whether that deflation reaches Cardiff is the near-term test for ap Iorwerth's majority.

Reform-run English county councils (Essex, Suffolk, Norfolk)

Essex named a City-trained efficiency lead over a budget where statute has already committed roughly 98% of spend; Suffolk simultaneously issued a pre-action letter against the reorganisation that will dissolve it. Reform-controlled authorities are spending public money on litigation their own sector lawyers expect to fail while their DOGE units face statutory constraints they cannot override.

Scottish Government (SNP under John Swinney)

Swinney rested the 72-55 Holyrood mandate on the combined SNP-Green bloc rather than his own party's 58 seats, seven short of the trigger he named; he has publicly conceded he has no plan if Westminster holds its veto. The constitutional argument is made; the enforcement route does not exist.

UK Government (MHCLG and Downing Street)

MHCLG has until 12 June to respond to Suffolk's pre-action letter and faces three further counties at the same stage; Downing Street rejected Holyrood's Section 30 demand as a spokesperson lobby line rather than a written statement, declining to open formal inter-governmental correspondence. Both decisions compress Reform's two main legal challenges into the same two-week window.

UK Government (Labour)

Westminster framed the youth justice transfer as a culmination of prior work rather than a precedent, refused a Section 30 order before the request arrived, and omitted both the Representation of the People Bill and any Wales Bill from the 13 May King's Speech. Starmer is described as open to a devolved-leaders summit in June.

Reform UK

Essex, Norfolk and Suffolk filed pre-action protocol letters framing their LGR challenge as mandate-consistent, while 22 Reform councillors departed in 14 days at an annualised rate nearly three times the 10 percent projection. Richard Tice defended the Harborne 5 million pound gift as unconditional, with no acknowledgement of Farage's two contradictory accounts on record.
