Donald Trump's presidential victory brings uncertainty for the UK, as his often unpredictable style prompts questions on future relations. Both UK and US leaders have engaged diplomatically, with Keir Starmer and foreign secretary David Lammy working to strengthen ties. Recently, Starmer and Lammy met Trump in New York, with Trump accommodating their visit - a gesture signalling diplomatic goodwill. Lammy has also made several trips to the USA, showing an effort to understand Trump’s 'America First' priorities. However, despite efforts at outreach, Lammy acknowledges potential friction, especially on European defence spending and the USA's shifting focus towards Asia. Concerns loom over future support for Ukraine, and there is apprehension about potential economic impacts, including tariffs and trade disagreements. While the UK has prepared for various outcomes, a Trump second term is expected to be marked by a transactional, sometimes tense, relationship that impacts both nations.
