**Nigel Farage triggered and won the August 13, 2026 Clacton by-election after resigning his seat in early July amid a parliamentary inquiry into possible financial impropriety.** He secured roughly 63% of the vote against a field of fringe and novelty candidates, with major parties boycotting the contest. The investigation has since resumed, but Farage has returned to the Commons as the sitting Reform UK MP for the constituency. With the seat now filled following the recent by-election and no announced plans or procedural triggers for another vacancy, traders assign a 70.5% probability that no further by-election will be called before the end of 2026. UK parliamentary rules require a vacancy through resignation, death, or disqualification for a new contest to occur, and current circumstances provide no evident catalyst within the remaining months of the year. The market reflects this stability in the constituency’s representation.
