UK PM Starmer blames Foreign Office for Epstein scandal, rejects resignation calls

UK Prime Minister Keir Starmer is rejecting calls to resign, attributing the Peter Mandelson-Jeffrey Epstein scandal to the Foreign Office. “Starmer out by June 30, 2026?” sits at 36% YES.

Market reaction

Starmer’s refusal to step down shifts attention to the Foreign Office’s handling of Mandelson’s vetting. The odds for Starmer’s exit by June 30, 2026 have held steady at 36% over the past 24 hours but are up from 18% a week ago. The December 2026 market shows odds at 64.5% YES, slightly down from 66% yesterday but up from 49% a week ago.

Why it matters

The term structure points to traders pricing in a potential catalyst in the second half of 2026. There’s a 28-point gap between the June and December contracts, suggesting the market expects developments that could increase pressure on Starmer’s leadership after the summer. The Foreign Office’s involvement and Mandelson’s ongoing legal issues feed that uncertainty.

Trading context

The “Starmer out” market has daily USDC volume at $27,552 across both June and December contracts. It takes just $3,464 to move the June odds 5 points, which makes the market vulnerable to larger trades. The biggest move yesterday was a 2-point drop, suggesting cautious positioning.

What to watch

Starmer’s deflection to the Foreign Office may buy time but doesn’t remove the pressure. At 36¢, a YES share pays $1 if Starmer is out by June 30, a 2.78x return. For that bet to pay off, the scandal would need to escalate within 71 days. Key triggers: internal Labour leadership bids from Angela Rayner or Wes Streeting, new revelations about the Foreign Office’s role, or developments in Mandelson’s legal proceedings.
