On the second day of his state visit to the United States, speaking before Congress, where he was repeatedly acclaimed with loud applause, King Charles III stressed the value and importance of the indispensable UK and US partnership.

The extent to which UK is exposed to the ongoing energy shock, as a consequence of the Iran war, and fears or rising inflation, was exposed by the British government’s borrowing costs that have risen to their highest level since the 2008 financial crisis.

The US-Iran conflict has propelled currencies from energy-exporting countries into the limelight, with windfall profits from exports of oil, gas and metals helping them to outperform the US dollar.

King Charles III delivered a 28-minute address on Tuesday to a joint session of the United States Congress in which he hailed the special relationship between London and Washington as one of the most consequential alliances in human history, in a speech that avoided any direct reference to the war against Iran or the Epstein case, two issues that have strained transatlantic ties in recent weeks. The address marked the centerpiece of the monarch's state visit to Washington, held in the framework of the 250th anniversary of American independence.

The United Arab Emirates announced on Tuesday its withdrawal from the Organization of the Petroleum Exporting Countries (OPEC) and the broader OPEC+ alliance, in a decision taking effect on May 1 that constitutes one of the most significant blows to the oil cartel in its more than six decades of existence.

King Charles III is preparing to deliver an address to a joint session of the US Congress at 3:00 p.m. local time on Tuesday, in which he will frame reconciliation and renewal as the defining themes of the bilateral relationship between London and Washington 250 years after American independence.

The Falklands sovereignty dispute returned to the centre of the diplomatic agenda this week with two developments of immediate impact: comments by Argentine Vice President Victoria Villarruel demanding that islanders “go back to England” if they “feel English” — despite the fact that in the 2013 referendum islanders voted by a 99.8% majority to remain British — and a disclosure published by The Telegraph that the United States had pressured the British government to tolerate the delivery to Argentina of F-16 fighter jets sourced from allied territory.

A new Brazilian digital platform began operating on Monday to cross-check social and environmental data and support the tracing of commodity chains linked to deforestation, land conflicts and other rural violations.

A 22-point manifesto published by Palantir Technologies on social media platform X has triggered a wave of international criticism over its ultranationalist and militarist tone, at a moment when the US data analytics firm for military and intelligence use has consolidated its position as one of the Pentagon's leading contractors. The document, posted on April 19, has accumulated more than 32 million views and condenses the thesis of the book The Technological Republic, written by the company's chief executive Alex Karp and head of corporate affairs Nicholas Zamiska.
