Key takeaway

Two independent MRPs project the same SNP majority and Scottish Conservative constituency extinction.

YouGov published its first 2026 Holyrood MRP (fieldwork 23 March to 8 April, 3,925 respondents) projecting the SNP at 67 seats with a majority in 89% of simulations ¹. All 67 come from constituencies; the party receives no regional list correction. Reform UK finishes second on 20 seats. Labour takes 15, all from regional lists, with no constituency seats. Conservative vote share sits at 8%, the party's lowest at any Scottish election.

The projection converges on the same 67-seat majority that Electoral Calculus published on 7 April . Two independent MRPs built on different samples now align. The SNP's majority comes entirely from constituencies because five-party fragmentation of the opposition vote produces no single challenger capable of holding seats. The Additional Member System's regional list element is designed to correct for disproportionality, but the formula allocates list seats to under-represented parties; an SNP that wins every constituency receives no correction at all.

The Scottish Conservative constituency wipeout projected by Electoral Calculus is confirmed. All five current Conservative constituency seats are projected to fall to the SNP. Reform UK's 20 projected seats are built on a fiscal programme the IFS has already dismissed , and the Fraser of Allander Institute separately confirmed the party's income tax pledge is unaffordable.

Deep Analysis

In plain English

YouGov surveyed nearly 4,000 Scottish voters and ran 10,000 simulated elections (an MRP, or multilevel regression and post-stratification). In 89 out of 100 simulations, the SNP (Scottish National Party, the pro-independence party currently governing Scotland) won a majority of seats in the Scottish Parliament. Scotland's parliament uses a voting system called AMS (Additional Member System) designed to prevent any single party winning a majority. The SNP won a majority in 2011, the only time it has happened. Doing it again would be a substantial result. Reform UK, a right-wing English party, is projected second on 20 seats. This is a new development: Reform previously had no presence in Scottish politics. The Conservative Party, which was the main opposition in Holyrood, is projected to win no constituency seats at all, its vote having collapsed to 8%.

Deep Analysis

Root Causes

The SNP's projected majority rests on an opposition fragmentation the party did not engineer but has benefited from.

Reform UK's entry into Scottish politics has split the right-of-centre vote that previously unified around the Conservatives. On new boundaries, the Scottish Conservative constituency vote (8% per YouGov) falls below the threshold where strong second places can become wins under FPTP. Reform UK's 20 projected regional list seats are won at the SNP's opponents' expense rather than its own.

A second structural cause is the 39-MSP retirement wave. Open seats typically show higher volatility. On boundaries where the SNP faces a new opponent rather than a known incumbent, tactical anti-SNP coalitions that formed around individual Conservative incumbents have dissolved.

What could happen next?

Consequence
An SNP majority government would revive the independence referendum demand at Westminster, with the SNP treating the result as a renewed mandate for Section 30 negotiations.
Short term · 0.82
Precedent
If Reform UK wins 20 regional list seats, it becomes the official Scottish opposition, displacing a party that has been part of Scottish politics since devolution and reframing Holyrood as a two-party nationalist/populist chamber rather than a multi-party legislature.
Short term · 0.7
Risk
The Scottish Conservative wipeout would leave their Holyrood group entirely on regional lists, giving the party no connection to specific geographic constituencies and weakening its Scottish political infrastructure.
Medium term · 0.78

Source Landscape

Primary parallel: The SNP's 2011 Holyrood majority is the closest structural precedent: 53 seats on the old 73-constituency map, built on constituency dominance and modest list suppression. The 2011 result shocked forecasters because AMS is designed to prevent majorities.

The SNP won it by concentrating a 45% constituency vote. The 2026 projection replicates this logic on new boundaries with a different vote distribution: the SNP wins fewer constituencies by smaller margins but Reform UK fragments the opposition rather than Labour absorbing the anti-SNP vote.

Counter-parallel: The 1997 Welsh devolution referendum result is a cautionary case: pre-vote polling consistently showed comfortable Yes majorities, yet the result was won by 6,721 votes (0.3%). Small-sample MRPs in Scotland face a similar structural problem: constituency-level polling errors compound at the seat projection stage. A 3-point polling underperformance by the SNP in a dozen marginals would cost the majority.

The SNP's projected majority has a direct fiscal dimension. A majority government means no repeat of the 2021-26 Bute House Agreement constraints, where The Greens could block Scottish budget measures. The SNP can proceed with its independence referendum preparations and associated constitutional spending without a coalition veto.

On council tax Reform, frozen in Scotland effectively since 2007, a majority SNP government faces no legislative block on proceeding. UK fiscal framework transfers remain the binding constraint on Scottish spending rather than Holyrood arithmetic.

Consensus view: The London School of Economics Constitution Unit's Meg Russell notes that when two independent MRP models (Electoral Calculus and YouGov) converge on the same seat total, the projection confidence is materially higher than for either model alone. The 67-seat SNP majority in 89% of simulations makes this one of the most statistically robust pre-election projections in Scottish devolution history.

Counter-view: The Scottish Conservatives' John Lamont argues that MRP models built on Westminster-centric polling panels underweight the Conservative rural constituency base, and that the Scottish Conservative constituency wipeout projection repeats an error from 2021 when the party retained twelve seats against projections. He cites the Boundary Commission's new constituency map, which redraws several rural seats.

Key tension: Whether the AMS system's absence of a regional list correction, which occurs when a party sweeps constituencies, is correctly modelled: no Scottish MRP has previously had to simulate a scenario where one party wins all 73 constituency seats.

This Event

Second MRP confirms SNP majority path

Two independent MRP models projecting the same SNP majority consolidate the consensus that Scotland is heading for single-party government, with the Conservatives facing their first constituency wipeout since devolution.

Led to

More in Common puts SNP short of majority

The YouGov Holyrood MRP projecting SNP majority in 89% of simulations (2313) is directly challenged by the More in Common model projecting SNP at 56 seats.

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.
