Key takeaway

A 7% Restore Britain splinter could split the right and hand Burnham the seat that gates the Labour leadership.

A Survation poll taken 18 to 22 May puts Andy Burnham on 43% in the Makerfield by-election against Reform's Robert Kenyon on 40%, with Restore Britain's Rebecca Shepherd on 7% ¹. Polling closes on Thursday 18 June. The 7% is the figure that matters: Restore Britain, fielding candidates to Reform's right, polls around 4% nationally , so it is running hot in exactly the seat where a few points decide everything.

Under first-past-the-post (FPTP, where the single highest vote takes the seat), a fractured right normally hands victory to the left, because splitting a bloc across two candidates wastes its votes. That arithmetic is now working against Reform. If most of Restore Britain's share would otherwise back Kenyon, it converts a Reform near-miss into a Burnham win. The historic right-of-Conservative splinters, UKIP and the BNP, let Labour hold marginal seats by the same mechanic.

Survation also measured the candidate himself: on a generic ballot with no names, Reform leads Labour by 11 points in Makerfield, but attach the names and Burnham leads by 3 ². That 14-point swing is the personal vote a sitting metro mayor brings, and it is doing as much work in this seat as the right-wing split.

Burnham needs this seat to re-enter Parliament, and the seat is the gateway to any challenge for the Labour leadership. Labour's National Executive Committee (NEC, the party's governing body) waved him through and the parliamentary party split 159 to 97 in the last count of nerve . A by-election in Greater Manchester, decided by a third party polling 7%, could set the terms of who eventually leads the governing party.

Deep Analysis

In plain English

Andy Burnham is currently the elected mayor of Greater Manchester, but he wants a seat in Parliament. Labour arranged for the Makerfield constituency to hold a by-election on 18 June so he can stand there. A by-election is a one-off vote for a single constituency, triggered when a seat falls vacant. A polling firm called Survation asked 504 local voters who they would support. With candidates' names attached, Burnham leads by 3 points. Without names, Reform leads Labour by 11 points in the same area. That 14-point difference is how much Burnham's personal fame is worth. There is also a new smaller party called Restore Britain, polling 7% in this seat against 4% nationally. If its voters would otherwise support Reform, the split could tip the result to Burnham even if Reform closes the gap.

What could happen next?

Risk
A Burnham win on 18 June would almost certainly trigger a formal Labour leadership contest, with knock-on consequences for Starmer's position and the government's legislative programme.
Precedent
Restore Britain's 7% in Makerfield will be read as a proof-of-concept by FPTP reform campaigners: a 3% over-performance on its national average demonstrates that right-fragmentation is a structural feature of FPTP under a four-party system, not a one-off anomaly.

Source Landscape

This story draws on neutral-leaning sources

Primary parallel: The Heywood and Middleton by-election in October 2014 is the clearest FPTP right-split precedent: UKIP polled 38.7% on a surge from the Conservatives, who fell to 14.5%, and Labour held the seat with 40.9% despite a dramatically reduced majority.

The structural mechanism was identical: a new right-populist party consolidated protest-right votes at the expense of the incumbent centre-right, splitting the non-Labour vote under FPTP and handing Labour a seat it would have lost on a consolidated right. Restore Britain plays the UKIP role in Makerfield, but at 7% rather than 38.7% the effect is proportionally smaller.

Counter-parallel: The Newark by-election in May 2014 shows a different outcome: UKIP ran at 25.9% but the Conservatives held the seat with 45.0%, demonstrating that a right-split does not automatically produce a Labour win if the incumbent right-of-centre vote is strong enough. Newark, however, was a safe Conservative seat in a very different regional context to Makerfield, which Reform leads on a generic ballot by only 11 points before Burnham's personal premium is applied.

Consensus view: The Electoral Reform Society has documented across multiple by-elections since 2014 that FPTP (first-past-the-post) structurally rewards consolidated vote blocs and punishes fragmented ones: a 7% Restore Britain share splitting from a 40% Reform candidate converts a probable Reform win into a near-certain Labour hold if even half of Restore Britain's voters would otherwise have backed Reform.

Survation's own methodology note on the 18-22 May poll flags the 14-point gap between the generic and named ballot as unusually large for a mainland English constituency, suggesting Burnham's personal-vote effect is materially bigger than his party's structural position.

Counter-view: A 'Burnham personal-vote' reading holds that most of the 14-point swing reflects his exceptional mayoral profile rather than the Restore Britain split, and that once voting day arrives, Restore Britain's voters in a Labour-leaning ex-industrial seat may simply stay home rather than vote for either Reform or Burnham.

On this reading, Kenyon's 40% is already discounting most of the Restore Britain bleed, and Reform's real ceiling is constrained by the constituency's demographic composition rather than the split.

Key tension: Whether the 14-point personal-vote premium is durable to polling day on 18 June, or whether Reform will close the gap as the national-question frame reasserts itself over the celebrity-candidate frame.

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.
