Recent UK developments have elevated Keir Starmer's position in trader consensus, with Labour suffering heavy local election losses that triggered over 80 MPs to demand his resignation or exit timetable, multiple ministerial departures, and analyst estimates of an 80% chance he leaves office this year. Gustavo Petro trails closely due to his fixed term ending in August 2026 after the May 31 presidential vote, where he is constitutionally barred from running again despite approval ratings near 47%. The narrow gap between these two reflects uncertainty over the precise timing of Starmer's potential ouster versus Petro's scheduled departure, while lower-probability options for leaders like Díaz-Canel face structural barriers such as limited opposition leverage. Upcoming UK leadership maneuvers or Colombia's election results could widen separation by clarifying which exit occurs first before 2027.
