Protests across Scotland as Trump plays golf at Turnberry
The President arrived at his resort on Friday night after talks with the Prime Minister.
Another day of protests is to be staged in Scotland while Donald Trump spends the weekend playing golf.
The US President flew on Air Force One to Prestwick Airport on Friday night for a two-day private stay at his Turnberry golf resort.
Demonstrations are being held in most large UK cities this weekend, as well as at Turnberry and Trump International in Aberdeenshire .
Campaigners are demonstrating against Trump administration policies including a travel ban against several majority-Muslim countries and separation of migrant families at the Mexican border.
Large crowds gathered at George Square in Glasgow on Friday, for a protest that attracted thousands of campaigners throughout the evening.
On Saturday, a national demonstration will be held at the Scottish Parliament in Edinburgh, along with a "Carnival of Resistance" in the Meadows area of the capital.
Trump's arrival at Turnberry was met with a huge breach of security, when a protester on a microlight flew over the building, with a banner billowing behind him.
The banner displayed the words "Trump well below par. #resist" and showed a Greenpeace logo on the canopy.
The president was standing outside the building and was quickly ushered inside.
Ben Stewart, from the campaign group, said: "Theresa May should not have dignified Trump with a visit to the UK. The vast majority of British people are appalled by his words and deeds.
"He is, simply, the worst president ever. That's why we flew over him with a message branding him well below par."
Nicola Sturgeon was not invited to meet Donald Trump during his UK visit, the Scottish secretary said.
David Mundell was speaking shortly after the President touched down at Prestwick.
The First Minister, who has been a vocal critic of Trump, will instead lead the Pride Glasgow parade on Saturday.
"The arrangements were made by the United States government and I understand they did not invite the First Minister," Mundell told STV News shortly after the President departed Prestwick for Trump Turnberry.
Asked whether the estimated £5m cost of policing the President's visit was value for money, Mundell added: "I think it's very important we give the person in that office the appropriate welcome to Scotland.
"There are security issues and they have to be addressed and that is why we have such a significant number of police around the visit."
The main focus of Mr Trump's visit was his meeting with the Prime Minister on Friday, which took place in the wake of a newspaper interview in which he said the Theresa May's Brexit plans would kill off a trade deal with America and Boris Johnson would be a "great prime minister".
At a press conference later in the grounds of the PM's country residence, Mr Trump insisted he "didn't criticise" the Prime Minister and hit out at "fake news".
The US president told Mrs May "whatever you do is OK with me" on Brexit, but urged her to "make sure we can trade together".
The Prime Minister said the United States is "keen" to do a deal with the UK.
"We will do a trade deal with them and with others around the rest of the world," she added.
