The US has been granted permission to use British military bases to launch attacks on Iranian missile storage depots and launchers, Sir Keir Starmer announced on Sunday.
London has given approval for RAF Fairford in Gloucestershire and the joint UK-US military base of Diego Garcia in the Chagos Islands to be used by Washington, according to British officials.
The UK prime minister said the move was “in line with international law”, as it underscored the “collective self-defence of longstanding friends and allies”, and would help safeguard British lives and interests. Gulf nations had urged London to do more to protect the region, he added.
