Labour's commanding parliamentary majority of around 156 seats makes passage of a no-confidence motion against the government before June 30 highly improbable, as opposition parties lack the numbers to prevail without unprecedented cross-party defections. Internal Labour unrest since May—including calls from dozens of MPs for Starmer to step aside and several ministerial resignations—has centered on party leadership rules requiring 20% of MPs to back a formal challenger, rather than triggering a Commons confidence vote. No such motion has been tabled, and with Parliament's calendar and the short remaining window, procedural barriers further reduce the chance of any vote occurring or succeeding. Traders' 90.5% implied probability on "No" reflects this structural reality over recent polling or speculation.
