Starmer’s June 2026 resignation amid collapsing approval ratings and Labour’s local-election losses has shifted the market toward two prime ministers by end-2027. Traders see an orderly handover to frontrunner Andy Burnham—now the clear successor after his recent by-election win—as the baseline scenario, with limited appetite for a snap general election before 2029. The 76.5% price on “2” reflects this expectation of short-term stability under the new leader. Prices at 50% for one, three, or four-plus outcomes capture residual uncertainty around Burnham’s longevity, potential Reform UK gains, or further internal Labour turbulence that could trigger additional changes before 2028.
