**Recent leadership transition and relative stability under Andy Burnham anchor trader expectations for limited further change.** Keir Starmer resigned in June 2026 amid sharply falling approval ratings and internal Labour pressure after poor local election results, with Burnham succeeding him as prime minister in July following an uncontested party vote. Burnham now leads a government with a substantial Commons majority inherited from the 2024 election. The next general election is not due until 2029, and Burnham has explicitly ruled out calling an early contest while committing to the existing manifesto. No major new catalysts—such as renewed leadership challenges, sharp economic shocks, or by-election reversals—have emerged since the July handover. This environment supports the market's strong consensus on two prime ministers total by the end of 2027 at 85.5% implied probability, while the modest 13.5% on three and 1.4% on four or more reflect the low assessed likelihood of another turnover before the deadline.
