Andy Burnham's first days in office have delivered a clear signal on national security. The new prime minister has approved continued American use of British military bases for defensive strikes against Iran.
This choice keeps in place the arrangement established by Keir Starmer back in March. RAF Fairford in Gloucestershire and Diego Garcia in the Indian Ocean remain available to US forces targeting Iranian command centres, launch sites, air defences and maritime assets. The operations aim to degrade capabilities that have been used to attack commercial shipping in the Strait of Hormuz.
Burnham was briefed on the ministerial discussions immediately upon taking office on 20 July. He agreed to stick with the existing policy rather than reopen it. The decision emerged in reports on 21 and 22 July, just as US strikes resumed following attacks that killed American service members.
The move stands in contrast to any instinct for hesitation. It puts practical cooperation and deterrence first. Securing vital shipping lanes matters more than ideological reservations, especially when hostile actors threaten the flow of global trade.
President Donald Trump spoke by telephone with Burnham shortly after he became prime minister. In that call Burnham set out the United Kingdom's commitment to securing the movement of shipping in the Strait of Hormuz. The message was unambiguous: Britain will stand with its closest ally when the stakes involve both security and prosperity.
This early continuity says something important about the new Labour government under Burnham. It suggests a recognition that threats do not pause for domestic transitions. Iranian aggression has already escalated. American responses have been framed as defensive, focused on protecting lives and trade routes. Allowing US access to British facilities is not an act of aggression but a measured contribution to collective self-defence.
