British Prime Minister Keir Starmer supports President Donald Trump’s military strikes against Iran. Starmer posted, "Iran’s nuclear programme is a grave threat to international security. Iran can never be allowed to develop a nuclear weapon and the US has taken action to alleviate that threat."

He said the security of the Middle East, however, remains a question following the U.S. strikes against Iran’s nuclear weapon processing facilities. "The situation in the Middle East remains volatile, and stability in the region is a priority."

Now, said Starmer, is the time for Iran to realize it needs to back down. "We call on Iran to return to the negotiating table and reach a diplomatic solution to end this crisis."

Trump ordered Air Force bombers to strike Iran’s nuclear material enrichment sites, key to the construction of nuclear weapons. The late Saturday strikes followed more than a week of Israeli attacks on Iran’s nuclear program sites after negotiations to get Iran to back away from nuclear weapons fell flat. Iran has threatened the U.S. with retaliation and said it would block the nearby Strait of Hormuz, a key oil shipping lane.

The Guardian reported that Starmer joined the leaders of Germany and France in a joint statement telling Iran not to make the situation worse. "We urge Iran not to take any further action that could destabilise the region."

Reuters reported Starmer had calls with the leaders of Oman and Jordan and that they agreed Iran should reopen negotiations rather than envelop a wider area in military or economic conflict.

Some Democratic congressional leaders in Washington want to block Trump from potential additional attacks on Iran. Most Republican leaders have said they support Trump's actions.
