Overview

• Trump and Starmer signed a UK–US science and technology cooperation deal, with Britain touting about £150 billion in US investment pledges including £31 billion for AI and a $30 billion Microsoft supercomputer program.
• At Chequers, Trump said Vladimir Putin had "really let me down" on Ukraine and urged Europeans to curb Russian oil purchases, as Starmer pushed for increased pressure on Moscow.
• The visit produced warmer personal ties but no breakthrough on US steel and aluminum tariffs, and Trump disagreed with UK plans to recognize a Palestinian state while urging a tougher UK response to illegal migration, including potential military use.
• Protests and political fallout trailed the trip, with four people bailed after projecting Trump–Epstein images on Windsor Castle and Trump saying he did not know sacked UK ambassador Peter Mandelson.
• On departure, the presidential helicopter diverted to a local airfield due to a minor hydraulic issue before Trump safely transferred to a backup aircraft for the flight home.
