US President Donald Trump arrived in London on Thursday on his maiden visit to the United Kingdom during which he will hold bilateral talks with British Prime Minister Theresa May over closer post-Brexit ties, amid mass protests planned around Britain against his controversial policies.
London Mayor Sadiq Khan has come under fire for his approval of a blimp featuring US President Donald Trump dressed as a baby.
The poll conducted this week said 63 per cent found Trump racist, and 74 per cent said he was sexist.
In a list of "actions to take", the warning recommended that Americans, "Exercise caution if unexpectedly in the vicinity of large gatherings that may become violent", "keep a low profile" and "be aware of your surroundings".
However, despite the welcome from May, many Britons remain deeply opposed to Trump's visit. "Trump would share that level of national identity and patriotism".
Police Scotland Assistant Chief Constable Mark Williams, said: "Clearly there is a significant protection operation in place for the President and this includes restrictions to the airspace in the Turnberry area. Are you honestly saying that the right to protest, the right to assemble, the right to free speech is limited by the ridicule it might cause to someone else?"
"This week we have an opportunity to deepen this unique trading relationship and begin discussions about how we will forge a strengthened, ambitious and future-proof trade partnership".
Mr Trump will then travel to Windsor Castle to meet the Queen before heading to Scotland for the private part of his four-day visit.
Along with trade and security links, 10 Downing Street said the other key areas to be discussed between Prime Minister May and President Trump included Brexit and the Middle East.
Trump was making his first trip to Great Britain as president after a tense summit with North Atlantic Treaty Organisation leaders in Brussels that began Wednesday and on the heels of ruptures in May's government because of the crisis over Britain's exit from the European Union. May welcomed the summit and said it could help address "malign activity" by Russia which Britain blames for a nerve agent attack in March on a former Russian double agent and his daughter in southwest England in March.
