A fresh agreement with Iran is taking shape, and the contours are already drawing fire from critics who have seen this film before. But sources close to the negotiations insist this time is different. The deal, which remains tentative, goes beyond the nuclear restrictions of the 2015 Joint Comprehensive Plan of Action and targets the very arteries of Iranian power: weapons, money and ships.
Leaked documents obtained by this newsroom reveal that the proposed framework includes a binding commitment from Tehran to halt ballistic missile development and to cease supplying drones and precision-guided munitions to proxies in Yemen, Syria and Lebanon. In exchange, the US and European signatories would unfreeze roughly $10 billion in Iranian assets held abroad and facilitate the return of sanctioned tankers currently detained in ports from Greece to Gibraltar.
But here is the rub. The UK, which was heavily burned by the previous agreement, is refusing to sign off without ironclad verification mechanisms. A senior Foreign Office official told me: “We were sold a promise of inspection and got a photo op. Not this time.” Britain is demanding real-time monitoring of Iranian ports and shipping lanes, including the right to board vessels suspected of carrying arms to proxies. Iran has so far rejected this, calling it a violation of its sovereignty.
The money trail is equally contentious. The deal proposes that Iran’s frozen funds be released in tranches, tied to verified steps on missile rollback. But the Treasury is worried that the money will simply be funnelled into the Islamic Revolutionary Guard Corps’ sprawling economic empire. “We’ve seen the same playbook in Lebanon and in Iraq,” a former MI6 officer said. “The IRGC is a state within a state. You give Tehran money, you are arming the IRGC.”
Then there are the ships. A key part of the deal involves the return of Iranian oil tankers seized for sanctions violations. These vessels, some of which are flagged in countries like Panama and Tanzania, would be allowed to resume shipments to China and other buyers. But British intelligence has flagged that several of these tankers have been used to deliver weapons to the Houthis in Yemen. “We are effectively unblocking an arms supply line,” a defence source said.
So why is Britain even at the table? The answer is strategic exhaustion. The US is withdrawing from the Middle East, the EU is desperate for Iranian oil to stabilise energy prices, and Tehran is now months away from a nuclear breakout. The new deal is a damage-limitation exercise. But the risks are enormous.
Iran has already made clear that it will not decommission any centrifuges. Instead, it has agreed to cap enrichment at 60%, a level that is weeks away from weapons-grade. This is not a limitation, it's a hair-trigger. And the promise to stop arming proxies? Previous agreements have failed because the IRGC has always found workarounds: false cargo manifests, ship-to-ship transfers at night, and front companies in Dubai.
One former nuclear negotiator told me: “The new deal is like putting a bandage on a bullet wound. The patient might survive the night, but you haven’t fixed the infection.” The real fear in Whitehall is that this deal will buy time only for Iran to perfect its missile technology and stockpile enriched material before the agreement collapses, as the last one did.
In short, Britain is wary because it has been here before. The new deal may differ on paper, but the same actors, the same flaws and the same cycles of deception remain. Until Iran allows boots on the ground in its ports and eyes on its bank accounts, no piece of paper is worth the ink it's written with.
