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

Democratic Unionist Party

Gavin Robinson rejects Sinn Féin's characterisation of the institutions as precarious, says the DUP is "committed to" delivering for the public, and will not be "goaded" into a dispute he attributes to Treasury funding rather than unionist bad faith.

Sinn Féin

Conor Murphy says Stormont power-sharing is in "a precarious place" and blames the DUP for lacking "the political will to make it work", while insisting his own party remains "wedded to power-sharing".

Council leaders in West Sussex and Cambridgeshire and Peterborough

Officers must recruit staff and set shadow budgets through the autumn for boundaries Whitehall has not yet drawn, after October's deferral cost three months of planning time without settling anything, while their May 2027 election date has not moved.

Restore Britain

Restore Britain beat the Conservatives into fifth place in its first mayoral attempt, evidence Rupert Lowe's party has already displaced the Tories as the default home for voters leaving the Conservative column on Reform's right flank.

Scottish National Party

The SNP, through deputy leader Keith Brown, calls Sarwar's peerage exit "the most undemocratic trick in the Westminster book", arguing Scottish Labour now runs on a caretaker leader chosen by patronage rather than by Scottish voters.

Conservative Party

The Conservatives finished fifth in Greater Manchester, beaten by Restore Britain, a party founded this year, in a contest the Tories once treated as a two-horse race against Labour.
