US President Donald Trump arrived here today on his maiden visit to the United Kingdom during which he will hold talks with Prime Minister Theresa May over closer post-Brexit ties and have an audience with the Queen, amid mass protests including a giant "Trump baby" in a nappy to oppose his controversial policies.
It will be a working visit, which will see him have meetings with the Prime Minister, British business leaders and the Queen.
Donald Trump will then visit the Queen with first lady Melania Trump at Windsor Castle before heading off to Theresa May's countryside home Chequers.
Although he will visit the USA ambassador's residence, he is largely avoiding central London, where the largest protests are expected Friday.

"Exercise caution if unexpectedly in the vicinity of large gatherings that may become violent", the embassy said in a list of advised actions, asking Americans to "keep a low profile" and "be aware of your surroundings". Thousands of protesters were expected to gather outside the luxurious residence later Thursday.
The largest protest is planned tomorrow afternoon, when over 50,000 protesters are expected to march from the BBC building in Portland Place to Trafalgar Square in the heart of London.
