Key takeaway

YouGov's final Holyrood MRP puts the SNP at 62 seats, three below Swinney's 65-seat referendum trigger.

YouGov's final Holyrood MRP, fielded 25 April to 5 May 2026 on a sample of 6,500-plus Scottish adults, projects the SNP at 62 seats in the 129-seat chamber, Reform UK at 19, Scottish Labour at 17, the Scottish Greens at 16, the Lib Dems at 8, and the Scottish Conservatives at 7 ¹. The SNP achieves an outright majority in 11% of simulations. The combined SNP-Greens pro-independence bloc clears the majority threshold in 99%.

The number matters because John Swinney named 65 seats as the trigger for a 2028 independence referendum . The earlier model spread, YouGov 67 in late March , Electoral Calculus 67, and More in Common 56 in April , has converged on 62, closer to the More in Common end of the range. The IFS noted in its closing-week sweep that no Scottish poll has put the SNP above 65 since the manifesto launch.

The distinction the campaign did not draw is between formal mandate threshold and functional parliamentary majority. Holyrood operates the Additional Member System (AMS), which combines 73 constituency FPTP seats with 56 regional list seats allocated by D'Hondt. Under AMS the Parliament can pass a resolution requesting a Section 30 order on a simple majority of 65 votes; the SNP-Greens combined deliver that majority in 99% of simulations. The 65-seat number Swinney attached to his own party was a campaigning device, not a constitutional one. Wes Streeting has already pre-empted the Holyrood vote by ruling Westminster will refuse, irrespective of the seat outcome.

Swinney addressed the gap on Tuesday 5 May, committing to a Section 30 vote 'on the first sitting day after appointment of the new government' and a draft referendum bill within 100 days ². 62 seats wins Swinney the chamber and loses him the test he set himself.

Deep Analysis

In plain English

Scotland votes tomorrow for its parliament, called Holyrood. The Scottish National Party (SNP), which has governed Scotland for nearly two decades, set itself a target: win 65 of the 129 available seats, and use that as the political argument for demanding another independence referendum in 2028. The final polls put the SNP at 62, three short. Three seats matters, and also turns out not to matter legally. The SNP plus the Scottish Greens, another pro-independence party, is projected to hold a parliamentary majority in 99% of polling simulations. That gives them enough votes to pass a motion asking Westminster to allow a referendum. But the UK Health Secretary, Wes Streeting, already said on 16 April that Westminster will say no regardless of the result. So Scotland faces a situation where the parliament may vote for a referendum the UK government has already decided to block. The 65-seat question is partly about whether SNP leader John Swinney faces an awkward post-election conversation about having missed his own number.

Deep Analysis

Root Causes

1. **Streeting's pre-poll Section 30 refusal.** By ruling out a Section 30 order before polling day, the Westminster government removed the political pathway the 65-seat trigger was designed to open. Swinney's mandate test was constructed on the assumption that a strong enough SNP result would make refusal politically costly for Westminster; Streeting's pre-emptive refusal collapsed that assumption before votes were counted.

2. **The 2023 Supreme Court ruling on unilateral referendums.** The court's November 2022 ruling that the Scottish Parliament cannot legislate for an independence referendum without Westminster consent removed the one constitutional alternative to a Section 30 order. This ruling closed the route under which seat count alone could have triggered action, leaving Section 30 as the only legal pathway.

3. **SNP membership and fundraising decline since 2023.** The SNP entered 2026 with roughly 72,000 members, down from 125,000 at peak post-2014; the party's fundraising difficulties contributed to a campaign operation below the 2021 level. This constrained the SNP's ground game in the regional list seats that determine the gap between 62 and 65.

4. **AMS regional list mechanics.** Holyrood's Additional Member System corrects for constituency over-performance on the regional list: an SNP that sweeps constituency seats sees its list vote translated into fewer regional seats. The more constituency seats the SNP wins, the harder it is to reach 65 seats total, because the D'Hondt regional list correction partially offsets constituency gains.

What could happen next?

Consequence
A Section 30 vote on the first sitting day of the new parliament is procedurally certain given the 99%-simulation SNP-Greens majority; its passage is formality without Westminster consent to the underlying order.
Immediate · 0.9
Risk
Swinney's 65-seat framing becomes a unionist talking point: he missed his own mandate threshold, weakening his public argument for a 2028 referendum regardless of parliamentary arithmetic.
Short term · 0.8
Precedent
A Holyrood parliament with a pro-independence majority but no Westminster agreement will test whether the constitutional convention approach Swinney's 100-day plan proposes can build visible momentum without a legal route to a referendum.
Medium term · 0.65

Source Landscape

This story draws on neutral-leaning sources

Primary parallel: Alex Salmond's SNP won 69 Holyrood seats in May 2011, the only time in the Parliament's history a single party held a majority, and used that result to negotiate the Edinburgh Agreement with David Cameron, securing a Section 30 order for the 2014 referendum.

Cameron's government chose to negotiate rather than refuse; the Starmer government's position, confirmed by Streeting before the poll , is categorical refusal regardless of the seat outcome. The 2011 bilateral route does not exist in 2026 because the UK government pre-closed it.

Counter-parallel: The SNP's 2007 minority government ran on 47 of 129 seats, governing without a majority through confidence-and-supply arrangements and avoiding a referendum entirely. A 62-seat result with Green support produces a stronger governing position than 2007 by any count. The 2007 precedent cuts against the idea that missing the 65-seat target constitutes a governing crisis, even if it creates a mandate-framing problem.

Consensus view: John Curtice, professor of politics at the University of Strathclyde and Britain's most-cited electoral statistician, has consistently maintained that the 65-seat figure Swinney attached to a referendum mandate is a political device rather than a constitutional threshold. The Scottish Parliament's standing orders require only a simple majority (65 of 129 votes) to pass a resolution; the SNP-Greens combined bloc clears that bar in 99% of YouGov's simulations regardless of whether the SNP reaches 65 seats alone.

Ailsa Henderson, professor of political science at the University of Edinburgh and co-author of the most comprehensive survey of Scottish constitutional attitudes, has noted that the Supreme Court's 2023 ruling against a unilateral referendum removed the one route through which the seat count would have had independent constitutional weight.

Counter-view: Constitutional scholars at the University of Glasgow's School of Law argue that a Section 30 order is a political negotiation, not a legal obligation Westminster must accept, so the SNP's formal seat count matters as bargaining leverage: a 65-seat SNP result would have made Streeting's refusal harder to sustain publicly than a 62-seat result that falls short of the party's own named threshold .

From Edinburgh, political scientist James Mitchell has written that referendum mandates operate in political culture rather than in law, and that Swinney's 65-seat number will be read by unionist politicians as the benchmark, not the 99%-simulation independence majority.

Key tension: Whether Swinney treats the SNP-Greens combined parliamentary majority as his operative mandate or holds to the 65-seat SNP-only threshold he campaigned on, a distinction Holyrood's standing orders cannot resolve and Westminster's refusal makes moot in the near term.

Different Perspectives

Local Government Association

New chair Eamonn O'Brien broke the LGA's neutrality on reorganisation for the first time since December 2024, telling the incoming prime minister the 'unprecedented scale' of disaggregation risks statutory services and asking him to adjust the LGR timetable, aligning the sector's institutional voice with the judicial review claims Suffolk, Essex and Norfolk have already filed.

Reform UK

Reform's £12m Harborne windfall from 2025 predates the 25 March retrospective crypto-donation ban, so the new law does not reach it; a live police probe into £500,000 of Cottrell donations continues, while the standards inquiry into Harborne's undeclared £5m gift is frozen since Farage vacated Clacton on 8 July.

Incoming Burnham government

Burnham secured 349 of the backing the NEC's 81-MP threshold required by 13 July, becoming Labour leader on 17 July and prime minister on 20 July without a members' ballot. He now inherits the LGR timetable the LGA wants him to adjust and a finance bill his own backbencher, Liam Byrne, is trying to harden further via amendment NC34.

Rupert Lowe / Restore Britain

Lowe called Farage's Clacton contest a 'Reform-sponsored media circus' and kept Restore Britain out of it, pledging instead to stand in the second by-election he expects the Harborne inquiry to force later this year. The boycott doubles as a signal that Restore Britain, not Reform, will contest the 'real' vote.

Kemi Badenoch / Conservative Party

Badenoch dismissed Farage's Clacton contest as a 'fake by-election' and joined the boycott, but reserved the right to fight a genuine second contest if Greenberg's inquiry forces one. The Conservatives are betting their real fight comes in autumn, not July.

Rhun ap Iorwerth / Plaid Cymru

Ap Iorwerth defended a £145m NHS allocation at First Minister's Questions on 1 July, blaming a graduate-nurse shortfall on 2022 training decisions taken before his Plaid-led government took office in May. Answering for choices his government did not make gives his new administration its first real accountability test.
