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.
