Recent parliamentary by-elections in the UK have followed MP resignations, including Keir Starmer’s departure from Holborn and St Pancras in September 2026 and Nigel Farage’s earlier exit from Clacton. No new Westminster vacancy currently has a confirmed polling date. Trader attention centers on the ongoing Parliamentary Commissioner for Standards inquiry into Farage’s undeclared financial interests, with findings expected imminently after Parliament’s return. A recommended suspension exceeding ten sitting days could trigger a recall petition in Clacton, potentially forcing another contest before year-end. Broader factors include routine risks of further resignations, health-related vacancies, or party defections amid shifting parliamentary arithmetic under Prime Minister Andy Burnham. Local council by-elections continue on a regular schedule but do not directly influence Westminster timing.
