Rob Yates, a Green Party candidate, won the Cliftonville division of Kent County Council on 9 April 2026 with 2,068 votes against Reform UK's Marc Rattigan on 1,767, a 26.7-point swing on 37.69% turnout. 1 The seat had been vacated after Reform councillor Daniel Taylor, elected on a comfortable margin in May 2025, was jailed in March for controlling and coercive behaviour towards his wife.
Cliftonville is a single ward of roughly 5,300 ballots, and the magnitude needs that caveat. The direction does not. This is the first ballot-box confirmation that YouGov's Labour-Green polling parity at 16% each translates into seats held by opponents, not a headline figure. It is also the first concrete instance of the 70-councillor Reform attrition pattern , which until this week read as an administrative abstraction. A vetting failure, a criminal conviction, a vacancy, and a loss: the sequence is now fully visible.
Two national figures contested a ward of five thousand voters. Green leader Zack Polanski campaigned in Thanet with former co-leader Caroline Lucas; Reform finance chief Robert Jenrick canvassed the opposite corner. That is what a local by-election with national reading attached looks like, three weeks before 7 May.
