Recent high-profile resignations, including former Prime Minister Keir Starmer's departure from Holborn and St Pancras in September 2026, have established a pattern of vacancies in the current parliament under Prime Minister Andy Burnham. As of mid-October, no new Westminster by-election writ has been issued, shifting trader attention to potential triggers such as MPs stepping down for health reasons, other elected roles, or internal party pressures ahead of the 2029 general election. Local council contests continue on scheduled dates, but parliamentary timing remains uncertain and dependent on individual announcements rather than fixed procedural deadlines.
