British Prime Minister Keir Starmer and German Chancellor Friedrich Merz signed the 'Kensington Treaty' aimed at combating smuggling, enhancing defense exports, and strengthening trade ties. This treaty marks a significant step in UK-Germany relations post-Brexit, with commitments to criminalize migrant smuggling and improve military cooperation. The leaders also discussed boosting support for Ukraine and fostering economic collaboration, including a new cross-border rail link and educational exchange opportunities.
