The Conservatives gained Dereham Toftwood on Breckland council from Labour on 16 July 2026, with Reform UK a strong new second on 36.9% and Labour's share down more than 35 points 1. On the same night the Green Party gained Fletton and Woodston on Peterborough City Council, also from Labour, with Reform again holding second on 29.7% 2.
The Fletton and Woodston seat fell vacant after a Labour councillor quit alleging "sustained bullying" over her push for closed-circuit television (CCTV) in taxis 3. Neither result unseated Reform; both unseated Labour, the same pattern visible in Reform's own loss at Old Catton the same evening.
Read across the three contests, Reform lost only where it was defending its own seat and grew where it attacked a Labour incumbent. Labour lost in all three. Burnham's party changed leaders this month to relieve exactly this pressure , and the first by-elections of his premiership deepened it instead.
