Sterling Slips as Markets Eye Post-Starmer Leadership Transition

Andy Burnham, the newly elected MP for Makerfield, has emerged as the clear frontrunner to replace Starmer after rival Wes Streeting withdrew his candidacy on Monday. Analysts at Handelsbanken suggest the market is pricing in a stable transition, specifically avoiding a repeat of the volatility that defined Liz Truss’s tenure in 2022. Attention has now shifted toward the selection of a new finance minister, with betting markets currently favoring Streeting over Ed Miliband for the role.

Despite the political maneuvering, the economic backdrop remains grim. S&P Global’s composite Purchasing Managers' Index fell to 49.4 in June, marking the sharpest contraction in business activity since April 2025. The services sector, which dropped to 48.7, remains a primary drag on growth. Economists at Pantheon Macro warn that while Starmer’s exit may resolve immediate leadership jitters, the lack of clarity regarding Burnham’s policy platform will likely keep businesses in a state of prolonged hesitation, further suppressing GDP growth.
