Trump arrives in UK for first visit as president amid protests and tensions with allies

US President Donald Trump touched down at London's Stansted Airport on Thursday to begin a long-planned visit to the UK. During his three-day trip Trump will meet with UK Prime Minister Theresa May and the Queen. The visit is expected to be marked with large-scale protests across the country and comes after Trump took a harsh stance on the United States’ European allies during a NATO summit in Brussels. Last year, Trump cancelled a similar visit to the UK, during which he had been expected to open a new US embassy in London.
