Context:

President Emmanuel Macron's state visit to the United Kingdom, hosted by King Charles III, is marked by significant pageantry but aims for substantial diplomatic outcomes amidst both leaders facing political challenges at home and abroad. The visit, the first since Brexit, focuses on enhancing cooperation between France and the UK, particularly in addressing migrant crossings in the English Channel and reinforcing support for Ukraine against Russia. Discussions are expected to include a potential 'one-in, one-out' migrant agreement and strategies for European defense autonomy given uncertainties around US commitments. Despite differing approaches to US President Trump, Macron and UK Prime Minister Keir Starmer share common interests in addressing security and trade issues. The leaders are expected to explore extending nuclear deterrence within Europe, reflecting broader concerns about security in the region as they navigate complex international dynamics and domestic political landscapes.

• The state visit also addresses European defense strategies, with France considering extending its nuclear umbrella to other European nations, reflecting concerns over the reliability of US defense commitments.

• Macron and Starmer's differing approaches to US President Trump highlight tensions in transatlantic relations, with Macron taking a more provocative stance compared to Starmer's alignment, yet both leaders remain united on the importance of European cooperation.

• Trade relations with the US pose another potential conflict, particularly if the EU rejects a framework agreement similar to that negotiated between the UK and the Trump administration.
