UK polls show Andy Burnham short of majority despite lead over divided right

Seat projections from MRP polling

Two separate multilevel regression and post-stratification (MRP) surveys published ahead of the Labour Party conference in Liverpool show Labour leading in seats while falling short of an absolute majority. A YouGov survey of 17,000 respondents, conducted between 23 August and 18 September 2026, projects Labour to win 241 seats in the 650-seat House of Commons. The same poll places the Conservatives on 130 seats and Reform UK on 123 seats, with the Liberal Democrats securing 71, the SNP 40, Plaid Cymru 15, and the Green Party nine. In national vote share averages, Labour holds 26 percent compared to 23 percent for Reform UK and 20 percent for the Conservatives.

A separate MRP model conducted by Survation and 38 Degrees between 20 August and 4 September 2026 surveyed more than 8,000 voters. It estimates Labour winning 272 seats with 28 percent of the national vote, representing 42 percent of parliamentary seats. Survation places Reform UK in second place with 153 seats and 24 percent of the vote, which would make Nigel Farage the leader of the opposition, while the Conservatives drop to third place on 85 seats.

Snap election speculation and party reactions

The polling results arrive as Conservative leader Kemi Badenoch suggested Prime Minister Andy Burnham might call a snap election in December 2026. Burnham currently leads a government holding a working majority of 166 seats and does not need to hold an election until 2029. Downing Street officials have discussed theoretical polling thresholds required for an election, though the prime minister has publicly ruled out an early vote. Labour figures remain opposed to risking their current majority, recalling Gordon Brown's aborted election plans in 2007 and Theresa May losing her majority in 2017.

I think Andy Burnham is a gambler.

Cabinet members have pushed back against suggestions of an early dissolution. One unnamed cabinet minister described the proposal as completely insane, noting that no Labour MPs support the idea. Opposition parties have nevertheless started procedural preparations for an early national campaign. Liberal Democrat leader Ed Davey confirmed that his party has established a manifesto working group ahead of its typical schedule.

We don't normally do it this early.

Tactical voting and the split right

The Survation study identified that progressive voters returning to Labour could alter the balance in closely contested constituencies. Twice as many voters have returned to Labour from the left as from the right since April 2026. The research identified 200 marginal seats decided by margins under five percentage points, where a swing of two to three points could move approximately 100 seats. In scenarios where progressive voters engage in tactical voting to oppose Reform UK candidates, Reform seat totals drop while Labour and the Liberal Democrats gain.

The research categorises the progressive electorate into five distinct segments sharing concern over living costs and the National Health Service. These groups include older, economically left-leaning rooted traditionalists and socially liberal open-hearted idealists. While Keir Starmer's previous strategy targeted older conservative voters prior to the 2024 general election, Burnham's current platform focuses on uniting left and centre voters while the right remains divided between the Conservatives and Reform UK.

The Holborn and St Pancras test

Attention within Westminster has turned to the upcoming by-election in Holborn and St Pancras following Keir Starmer's decision to step down from parliament. Starmer announced his departure from the Commons earlier in September 2026 after resigning as prime minister and Labour leader in July. Green Party leader Zack Polanski has confirmed his candidacy for the vacant London seat. Both Labour and Reform strategists regard the contest as a metric for whether left-wing voters are consolidating behind Burnham's administration. A decisive victory over Polanski would indicate reduced voter leakage to the Greens before the party convenes in Liverpool.
