The mayor of London has said he approved the flying of a giant blimp depicting President Trump as an angry, orange baby near parliament as it is an expression of free speech. His comments on militant attacks in Britain and his re-tweeting of anti-Muslim videos posted by a leader of a far-right United Kingdom party sparked anger.
It explains that "numerous demonstrations" have been planned for President Trump's visit between July 12 and 14, with most of those in central London, and large crowds expected.
They stated that people should "be aware of your surroundings" and "exercise caution if unexpectedly in the vicinity of large gatherings that may become violent" as well as monitor local media for updates.
The main demonstrations, which are set to be attended by over 50,000 people, will start outside the BBC building in Portland Place, yards from Oxford Circus at 2pm on Friday July 13.
Demos on Thursday include one near Blenheim Palace in Oxfordshire where Mr Trump will attend a black-tie dinner, and another not far from the U.S. ambassador's residence in Regent's Park, where Trump and his wife Melania will stay overnight.
After the North Atlantic Treaty Organisation summit, Trump will head to England, where Prime Minister Theresa May's government is in turmoil over her plans for exiting the European Union.
He is also expected to visit Scotland - where he owns two golf courses - before heading back to the US.
On Tuesday, Trump left for a weeklong Europe trip that includes a meeting with Russian President Vladimir Putin in Finland and the North Atlantic Treaty Organisation summit in Brussels.
Relations between Britain and Russia are at a post-Cold War low since May blamed the Kremlin for the poisoning of former Russian agent Sergei Skripal with a Soviet-era military nerve agent in March.
