US moves to reopen Strait of Hormuz as ships remain stranded
US ships moved to guide stranded tankers through Hormuz as Labour nerves over Starmer’s future grew, but the numbers still make a coup harder than the headlines suggest.
Hundreds of ships remained stranded in the Strait of Hormuz as a U.S.-led effort began to guide commercial traffic through one of the world’s most exposed energy chokepoints, while in London the talk of a Labour leadership challenge to Sir Keir Starmer continued to run ahead of the arithmetic.
The strait carries about one fifth of global oil and gas flows, and early May shipping data showed transits down to their lowest level since the opening days of the 2026 Iran-US-Israel conflict. The U.S. Navy began a task force operation on Monday, 4 May 2026, to help move vessels through the waterway, but shipping firms were still waiting for details as Iran insisted it remained in control of the route. The first day of the effort also coincided with renewed attacks on ships, underlining how fragile any reopening would be.
A Europe-led push to restore passage has been under discussion since April, with more than 30 countries involved in early planning and the United Kingdom and France helping to lead the coalition. That broader diplomatic and maritime response now collides with a market already shaken by the disruption: when Hormuz is constrained, energy prices, freight costs and supply lines all move at once, and the consequences are felt far beyond the Gulf region.
The political noise at home is easier to generate than the numbers required to force Keir Starmer from office. Labour’s rules now require an incumbent challenger to secure nominations from 20% of Labour MPs. With 405 Labour MPs, that means 81 nominations. The threshold was raised from 10% to 20% in 2021, making a formal challenge harder than the speculation suggests.
Starmer became Labour leader in 2020 and prime minister on 5 July 2024, which means the current chatter is arriving early in his premiership rather than after years of entrenched fatigue. Wes Streeting, Angela Rayner and Andy Burnham are among the names being linked to possible leadership moves ahead of the May 2026 local elections, but the rules still matter more than the rumours. Streeting is said in some reports to have enough backing to trigger a contest, yet that remains speculation, not a declared race.
For Starmer, the test is durability: can he project authority at home while allies scramble to keep shipping moving through Hormuz? For Britain and its partners, the answer will shape both the cost of energy and the credibility of governments trying to look steady in a period of rising pressure.
