# Starmer says UK will let U.S. use bases for defensive strikes on Iranian missile sites
Prime Minister Keir Starmer says the United Kingdom has agreed to a U.S. request to use British military bases for what he described as defensive strikes on Iranian missile sites, while stressing that Britain itself will not join offensive action.
The BBC reported that the decision applies to U.S. operations using British bases, with RAF Fairford in Gloucestershire and Diego Garcia in the Indian Ocean likely to be involved. Starmer framed the move as part of collective self-defence and said it was meant to protect British lives and those of allies in the region.
His statement marked a notable shift after earlier caution over the legal basis for any role British territory might play in a U.S. campaign against Iran. The prime minister said the UK had learned lessons from the mistakes of Iraq and that it was not involved in the initial strikes. He repeated that Britain would not join offensive action now.
That distinction is central. Allowing a partner to use bases is not the same as taking part in a strike, but it does place the UK squarely inside the logistics of the operation. Starmer defended the move by saying the specific purpose was to destroy missiles at source and reduce the danger to British personnel, regional partners and civilians.
The announcement came while the Middle East was already under intense pressure. The BBC said a British RAF base in Cyprus had been hit by a drone strike hours earlier, though no casualties were reported and the source of the drone remained under investigation. Starmer said British aircraft were already in the air as part of defensive operations and that the government was working to protect nationals in the region.
The government also published a summary of its legal position, saying the use of force can be lawful in self-defence when it is necessary and proportionate. That legal framing is likely to be scrutinized in Parliament, where opposition leaders immediately raised objections.
The politics are not straightforward. Conservatives accused the government of hesitating, Liberal Democrats warned against complicity in illegal military action, and other parties attacked or defended the decision in sharply different terms. The same announcement therefore carries three layers of significance: military, legal and political.
For now, the practical message is that Britain has chosen to support a limited U.S. operation without joining the strike campaign directly. That may satisfy Washington’s operational needs, but it will not quiet the larger debate about how far the UK should go in a fast-moving confrontation with Iran.
