A British spokesperson confirmed that ministers held discussions on Friday regarding the ongoing conflict and Iran’s disruption of the strategic waterway. Following the meeting, they agreed that existing arrangements allowing the U.S. to use UK bases for regional defence would also cover operations aimed at weakening missile systems threatening maritime activity.
Reacting to the decision, Iran’s Foreign Minister, Seyyed Abbas Araghchi, warned that Tehran views the UK’s action as direct involvement in the conflict, describing it as participation in aggression. He also criticised Britain’s stance as biased in favour of the U.S. and Israel during a conversation with his British counterpart.
Prime Minister Keir Starmer had earlier stated that Britain would not be drawn into a war with Iran and initially declined a U.S. request to use its bases, citing the need to ensure any military action complied with international law.
However, his position shifted after Iran launched attacks on British allies in the Middle East. The UK subsequently granted the U.S. access to key facilities, including RAF Fairford and Diego Garcia, a joint UK-U.S. base in the Indian Ocean.
Meanwhile, Donald Trump has criticised Starmer during the conflict, accusing Britain of not offering enough support to the United States.
Despite the authorisation, the UK government has called for urgent de-escalation and a quick resolution to the conflict.
The decision marks a broader involvement by Britain, moving beyond its earlier role of intercepting Iranian missiles and drones targeting its forces and allies.
In response, Iran has effectively blocked oil shipments through the Strait of Hormuz, a critical route for about one-fifth of global oil supply, raising fears of a worldwide energy crisis.
The conflict involving Iran, the United States, and Israel has now entered its fourth week, with casualties continuing to rise on all sides.
