Electoral Calculus published a Multilevel Regression and Post-stratification (MRP) model of the 6 May 2026 Holyrood election on 7 April 2026, based on a fieldwork sample of 4,105 respondents taken between 13 and 31 March. The model projects the Scottish National Party on 67 seats, two above the 65-seat majority threshold in the 129-seat chamber. All 67 projected seats come from constituency wins; Electoral Calculus allocates the SNP zero regional list seats.
The projection is methodologically unusual because the Additional Member System (AMS) was designed to prevent exactly this outcome. Regional list seats are distributed by a corrective formula that subtracts constituency wins from each party's vote share, meaning constituency over-performance normally drains a party's list entitlement. Electoral Calculus director Martin Baxter has argued the 67-seat projection requires the SNP to concentrate its vote above the model's historical tolerances, a scenario produced by five-party fragmentation of the anti-SNP vote rather than by any SNP surge.
The model is the first Holyrood projection of an outright SNP majority since 2011. No such majority has occurred since Alex Salmond's 2011 win, which produced the 2014 independence referendum on a 55-45 No result. A projected repeat lands on a chamber already losing a record 39 MSPs to retirement, and reframes the April campaign around a question the polling had not previously been asked to answer.
