Britain risks escalating tensions with Iran by proceeding with plans to de-mine the Strait of Hormuz, a critical global shipping channel, during the official mourning period for former leader Ayatollah Ali Khamenei. The operation, undertaken in conjunction with France and Oman, comes despite an apparent request from Tehran to cease military activities.
In a joint statement with French President Emmanuel Macron, Sir Keir Starmer announced that British forces have agreed to collaborate with Oman "to ensure that its sovereign territorial waters are safe for navigation." This declaration follows past criticism from the United States regarding allied responses to the U.S.-Israeli conflict with Iran, and the move is seen as an attempt to signal solidarity with the U.S.
The de-mining operation is scheduled to take place as Iran prepares for a multi-day funeral for Khamenei, who died in airstrikes over four months ago. Up to 20 million people are expected to attend the funeral, which is being framed by Iran as a significant propaganda event. The fragile ceasefire agreement has enabled the timing of the funeral ceremonies.
A Whitehall source expressed concern that the planned operation could disrupt the current period of calm. The Strait of Hormuz is a vital strategic waterway, and Iran has frequently used its control as leverage in peace negotiations. Proceeding with de-mining activities would directly contradict Tehran's request for a cessation of operations during the mourning period.
Starmer and Macron have reaffirmed their "shared commitment" to "uphold global security, freedom of navigation and international law." However, an unnamed source suggested that the leaders are also motivated to demonstrate to U.S. President Donald Trump, who has previously criticized allies for their defense spending and contributions, that they are prepared to "play their part."
President Trump has publicly criticized NATO allies' defense spending, particularly the U.S. commitment of $999 billion, stating on his Truth Social account that the relationship is not reciprocal. A senior UK military source reportedly described the £15 billion earmarked for defense by Starmer as an indication that "yet again we have failed to align ambition with resources."
Meanwhile, international dignitaries are beginning to arrive in Iran for the funeral. While Western leaders are not expected to attend, representatives from Iraq, Armenia, Turkey, and several Gulf states, including Saudi Arabia, Oman, and Qatar, are scheduled to be present. The former Ayatollah's body is currently lying in state in Tehran.
In a separate commentary, the outgoing British Prime Minister warned his likely successor, Andy Burnham, that significant attention must be paid to international relations, stating that domestic and international affairs are intertwined. He emphasized the current global conflict and the volatile nature of the international landscape, asserting that these challenges are unlikely to diminish.
