Labour's commanding parliamentary majority, secured in the 2024 general election, underpins the 90% trader consensus against a no-confidence vote targeting Prime Minister Keir Starmer by June 30, as opposition parties lack the numbers for success without unprecedented backbench revolt. Recent ministerial resignations, including Health Secretary Wes Streeting amid speculation of a leadership challenge, and backlash over the Mandelson envoy appointment scandal—where Parliament voted against an inquiry on April 28—have fueled internal party tensions and poor local election results, yet no formal no-confidence motion has been tabled in the Commons. Leadership challenges remain confined to Labour's internal processes, requiring 20% of MPs' signatures for a party vote, not a government-toppling parliamentary one. Absent mass defections or fresh scandals, traders see slim odds of escalation before the deadline.
