US President Donald Trump and first lady Melania Trump arrived in Britain on Monday on a state visit for three days. Trump, who will meet the queen at Buckingham Palace on the first day of his state visit, will be met by thousands of protesters in London the following day during a visit packed with pomp, pageantry and controversy that has seen numerous calls for its cancellation.
While Mr Trump has visited the UK before, this is his first official state visit involving far more ceremonial and Royal events.He and Queen Elizabeth will both deliver speeches at a state banquet at Buckingham Palace tonight.
Minutes before touching down, Mr Trump criticised Mayor of London Sadiq Khan, with whom he has clashed in the past. He tweeted that Mr Khan - who had earlier said the UK should "not roll out the red carpet" for Mr Trump - was a "stone cold loser", but the president added he was still looking forward to his visit. On Sunday, Mr Khan described the president as "just one of the most egregious examples of a growing global threat" and compared the language he has used to that of the "fascists of the 20th century".
Although Mr Trump has spoken of his admiration for Mrs May, there is expected to be differences of opinion during their talks, which begin on Tuesday.
