US President Donald Trump has reignited his longstanding feud with London Mayor Sir Sadiq Khan, sharply criticising Khan's leadership and blaming mass migration for changes in the city. In a recent interview, Trump described Khan as 'horrible' and 'incompetent', claiming London and other European capitals are in decline due to unchecked immigration. Khan responded by highlighting London's global appeal and suggesting Trump is 'obsessed' with the city.

The exchange comes amid a broader shift in US policy towards Europe, with the White House's new security strategy warning of 'civilisational erasure' in European nations due to migration and criticising the continent's handling of political and security issues. The document has sparked debate among European leaders, with some populist politicians welcoming the critique and centrist figures expressing concern over US interference.

Trump also weighed in on the ongoing conflict in Ukraine, expressing frustration with Ukrainian President Volodymyr Zelensky's response to US-backed peace proposals and asserting that Russia holds the upper hand in negotiations. The administration's stance has intensified transatlantic tensions and raised questions about the future of US-European relations.
