Westminster is on edge tonight. The White House has failed to secure a new Iran agreement. Downing Street sources are furious. They warned of an escalating nuclear threat. The deal was dead on arrival. Trump's team couldn't close it. The Iranians walked away.
This is a major blow for the Prime Minister. He staked his foreign policy on this. Now he faces a Commons backlash. Tory backbenchers are sharpening their knives. They say the PM is weak. The Labour front bench is circling. Corbyn's allies are calling for a full inquiry.
I spoke to a senior diplomat tonight. He was blunt. "The Americans don't get it. They think they can strong-arm Tehran. It doesn't work like that." The mood in the Foreign Office is grim. They fear a new arms race in the Middle East.
Polling data shows public anxiety rising. Most Brits don't want a war. But they don't want a nuclear Iran either. The PM is caught between two rocks. He needs a win. Fast.
Cabinet sources tell me the PM is considering a joint European approach. But the French and Germans are sceptical. They remember the last time Trump pulled the plug. Trust is gone.
Meanwhile, the nuclear clock is ticking. IAEA inspectors report worrying activity at Iranian sites. The world is edging closer to the brink. And Britain is left holding the bag.
This story is developing. I'll have more on the fallout tomorrow. But one thing is clear: this is the PM's biggest test yet. He's failing.
