Reform UK's group on Kent County Council has fallen from 57 seats to 47 between May 2025 and April 2026, a loss of ten councillors through expulsions, defections and resignations. 1 Kent was Reform's flagship 2025 gain at 57 of 81 seats; the group has shed roughly one councillor every five weeks since.
The Kent figure is the local concretisation of the national 70-councillor Reform departure total tracked by Mark Pack . 2 Reporting a national abstraction at a single council grounds the organisational story in one jurisdiction rather than a spreadsheet: the seat Rob Yates took from Marc Rattigan on 9 April is one of the 10, and the Reform councillor jailed in March is another. Kent's attrition rate of roughly 17% in under twelve months precedes any new electoral test and sits at the top end of the national spread.
