The Scottish Parliament closed nominations for the 2026 Holyrood election on 1 April 2026, with 39 MSPs not standing again. The retirement cohort is the largest in the Parliament's history since it was founded in 1999. The outgoing class includes former first ministers, cabinet secretaries and long-serving committee chairs whose combined service spans the whole devolution era.
The vote on 6 May is also the first under new constituency and regional boundaries, approved by the Second Periodic Review in October 2025, which is the first boundary revision since 2011. The review redrew lines across every region to reflect population changes over fifteen years. The combination of 39 retirements and 73 reconfigured seats means the next Parliament will contain a smaller share of incumbents than any since the chamber's founding. The Electoral Calculus MRP projecting an outright SNP majority lands on this disrupted map, not on the 2021 baseline.
The institutional consequences are practical rather than symbolic. Committee chairs, convenerships and select committee memberships rely on returning members with subject-matter continuity. A Parliament in which roughly a third of members are new and the remainder are contesting redrawn seats will spend its first session rebuilding the internal knowledge base that the retirement cohort is taking with it.
