The Scottish Parliament enters formal dissolution on 9 April 2026, two weeks after entering recess on 26 March. Dissolution is the legal moment at which the outgoing Parliament ceases to exist as a legislature; no member holds the title MSP between dissolution and the election of the new chamber on 6 May. Ministers retain their offices during the interval but cannot take votes from a legislature that does not exist.
Dissolution also triggers the regulated short-campaign spending limits under Scottish electoral law, the publication restrictions on government communications, and the commencement of pre-election Purdah for civil servants. Each has been in place at every Holyrood election since 1999, but 2026 is the first under the new boundaries approved by the Second Periodic Review in October 2025, which means many of the campaign rules apply to newly drawn constituencies for which no prior spending baseline exists.
The four-week window between 9 April and 6 May is the shortest effective window for voter engagement under the AMS system. It coincides with the period during which the Electoral Calculus MRP and any follow-up models will be weighed against doorstep reporting by the parties. Dissolution is procedurally unremarkable; its timing matters because it places the last four weeks of the campaign under rules that were drawn for a different map.
