UK police have stepped up security preparations ahead of US president Donald Trump's state visit, following the assassination of American political activist Charlie Kirk. Thames Valley Police and the US Secret Service are coordinating around venues including Windsor Castle and Chequers, where key events will take place.
The measures come amid planned protests, heightened political tensions and questions over whether the US attack could inspire copycat behaviour in Britain. Authorities emphasise that while no specific threat has been identified, security planning is being designed to cover every eventuality.
