The most consequential story out of Westminster this week is the leaked Pentagon memo proposing the US reassess its support for Britain’s claim to the Falkland Islands. The document, framed internally as a lever the Trump administration could pull to punish the UK for not backing the bombing of Iran, has forced Downing Street to publicly reaffirm that sovereignty over the islands is non-negotiable. The timing is brutal: King Charles begins a three-day state visit to Washington in the next few days, and this is now the backdrop. Whether the memo reflects genuine policy intent or was floated as a pressure tactic, it signals that the Trump White House is willing to weaponise the special relationship in ways previous administrations would not have considered.

Starmer has moved to get ahead of at least one irritant, promising imminent legislation to proscribe Iran’s Revolutionary Guard as a terrorist organisation. Previous governments had resisted this on the grounds that the Terrorism Act was designed for non-state actors. The shift matters because it removes a long-standing complaint from Washington and from parts of the Conservative opposition, and it comes directly in the context of the Iran pressure campaign.

On global macro, US equities are outpacing European markets sharply, with the FT noting Intel surging past dotcom-era highs as part of a broader tech-powered rebound. Wall Street appears to be treating the energy shock as manageable, at least for now. Separately, the US has sanctioned a Chinese “teapot” refinery, Hengli, for purchasing Iranian crude — the Treasury says it has generated hundreds of millions for Iran’s military. That is another notch in the Iran sanctions campaign and worth watching for knock-on effects on Chinese refining margins and oil flows.

On tech, Google has committed up to $40 billion into Anthropic, following Amazon’s investment earlier this week. The scale of capital now flowing into Anthropic from two of the largest cloud providers simultaneously is striking and raises real questions about competitive dynamics in enterprise AI. Cohere, meanwhile, has merged with Germany’s Aleph Alpha, positioning itself as a transatlantic alternative for governments and regulated industries that want AI infrastructure outside the US hyperscaler ecosystem. For anyone thinking about European AI policy or sovereign cloud exposure, that combination is worth noting.

King Charles’s state visit to Washington begins in the next 48 hours, and given the Falklands memo and the IRGC proscription announcement, the first day of meetings will be closely watched for any public signals from Trump on where the bilateral relationship actually stands.
