## Article Body
A recent YouGov MRP poll has revealed that Labour is experiencing declining support in London boroughs, exposing the fragmentation of the UK’s two-party system. The poll indicates that Labour is projected to lead in only 15 of the 32 London boroughs, a decrease from 21 in 2022. This decline is compounded by the rise of Reform UK and the Green Party, which are gaining traction on both the progressive and conservative flanks of Labour’s base. Nationally, Labour’s polling stands between 18-26%, with Reform UK and Greens eroding its traditional support. These shifts reflect a broader realignment in British politics from class-based to social conservative-liberal divides, posing challenges to Keir Starmer’s leadership ahead of the May 2026 local elections.
## Market Interpretation
The observed decline in Labour’s support and the rise of Reform UK and the Greens could be supportive of a YES outcome in the “Starmer out by June 30, 2026” market. This market’s current pricing suggests a moderate impact, reflecting a potential for leadership change if Labour’s performance in upcoming elections is poor.
