In Pictures: UK protests against President Donald Trump's visit

A large balloon depicting the US president as a giant infant will be allowed to fly over London during the president's four-day visit to the UK after the capital's Mayor Sadiq Khan gave his permission. Scottish police, however, said that the balloon could not fly over the Turnberry golf club Trump owns on the west coast of the country.

Trump and his wife, Melania, met British Prime Minister Theresa May and her husband Philip for a formal dinner at Blenheim Palace in Oxfordshire on Thursday. Hundreds of protesters descended on the castle to voice their opposition to the president's visit.

Most of the protests against Trump have taken aim and his anti-immigrant rhetoric, as well as his administration's policy of separating undocumented parents and children who cross the US border. Although Trump has said this practice will be stopped, thousands of children remain separated from their parents and face great difficulty locating their relatives.

Despite the protests, Trump insisted ahead of his trip to the UK that he was well-liked in the country. "I think they like me in the UK. I think they agree with me on immigration," he told reporters in Brussels. He then reminded the press that his mother was from Scotland.

As the Trumps dined with the Mays, protests in the British capital took place outside Winfield House, the residence of US Ambassador Woody Johnson. The Trumps will be staying with Johnson on Thursday night, one day before a mass demonstration against Trump's policies is set to take place in London.

Last year, activists began circulating a petition to block a state visit from Trump that eventually made its way to the floor of Parliament. In the end, the president canceled his visit before the UK government took any official steps.
