Seyyed Abbas Araghchi criticised the UK’s “negative and biased” stance toward the US-Israeli assault on Iran during a call with his British counterpart.

Araghchi warned that granting America access to UK bases “will certainly be considered participation in aggression.”

However, in response to the allegation, a spokesperson of the UK Prime Minister told reporters the UK granted the United States access only “for a specific defensive and limited purpose” in response to Iran’s strikes across the Middle East.

“Our position has been crystal clear from the outset. We didn’t participate in the initial strikes, and we’re not getting drawn into the wider war,” the spokesperson said.

According to reports, the British Prime Minister Keir Starmer initially refused Washington’s request to use UK military bases for its attacks on Iran, with the PM considering the strikes illegal.

However, Starmer joined the defence against Iran’s retaliation after Iranian forces attacked British military assets in the Middle East.

Gkingmusik  reported earlier that Starmer said his country accepted a United States request to use British bases for defensive strikes against Iranian missiles in storage depots or launchers.

“The United States has requested permission to use British bases for that specific and limited defensive purpose. We have taken the decision to accept this request to prevent Iran firing missiles across the region,” Starmer said at the time.

Tehran’s warning escalates diplomatic tensions between Iran and Britain as the conflict between Iran and the United States and Israel enters its fourth week.
