The Scottish National Party (SNP) won 58 of 129 Holyrood seats on Thursday 7 May 2026, seven below the 65-seat threshold John Swinney named in his 16 April manifesto launch as the trigger for a 2028 independence referendum . Holyrood turnout was 53.0 percent, down 10.5 points on 2021. Swinney remains as caretaker First Minister and is expected to form a minority SNP administration with informal support from the 15 Scottish Greens.
The 58-seat result sits between More in Common's pre-election projection of 56 and YouGov's final Holyrood MRP of 62 . Both models bracketed the actual count within seven seats. Additional Member System (AMS), the mixed ballot that combines constituency seats with regional list top-ups to achieve proportionality, behaved as a halfway house between Wales D'Hondt's one-seat-per-party accuracy (event-02) and England FPTP's 894-seat miss (event-00). The PR component disciplined the projection; the FPTP component introduced the residual error.
Section 30 of the Scotland Act 1998 is the route to a legal independence referendum: Westminster grants Holyrood a temporary statutory power to legislate for one. The 2022 UK Supreme Court ruling in Lord Advocate's Reference settled that Holyrood cannot legislate for a referendum without a Section 30 order regardless of seat count. Westminster refused a Section 30 order at the SNP's 64-seat 2011 majority and the 2019 mandate after the 2021 Holyrood victory. At 58 seats, there is no fresh majority on which to base a renewed request. The constitutional question is no longer whether Westminster will grant a Section 30 order; it is whether the SNP attempts a unilateral consultative-only ballot, knowing the Supreme Court has already ruled such a vote ultra vires.
The Electoral Commission has not yet published a Voter Authority Certificate breakdown of the turnout drop. Whether the 10.5-point fall reflects voter ID friction or campaign fatigue is the first material question for the Commission's post-election review. A friction explanation puts the Commission and Holyrood ministers under immediate pressure to revise voter ID guidance before the next ballot; a fatigue explanation hands the SNP a different problem, one of mobilising its own voter base after a decade in office.
