A £2,600 Polymarket bet has been placed on the outcome that Prime Minister Keir Starmer will still be in office past June 23, implying an ~18% chance he remains PM on that date, according to the market data.
The large trade by the user 'Frail-Possible' suggests some confidence that Starmer will withstand any potential challenges to his leadership in the coming months, though the market still sees a significant chance he could depart before the end of June.
