Donald Trump has landed in Scotland on the second day of his tumultuous visit to the UK.

The US President and his wife, Melania Trump, touched down at Prestwick Airport aboard Air Force One on Friday evening before travelling to Trump Turnberry in Ayrshire.

He is expected to spend the weekend golfing at one or both of his golf courses in Scotland.

Trump's arrival at the Turnberry luxury resort 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.

Demonstrations are being held in most large UK cities this weekend, as well as at Trump International in Aberdeenshire and Turnberry in Ayrshire.

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, for a protest that attracted thousands of campaigners throughout the evening.

A wall was built by protesters, with each contributor drawing a picture or writing a statement on a block.

Political leaders including Scottish Greens co-leader Patrick Harvey and Scottish Labour leader Richard Leonard spoke out at the rally.

Mr Leonard said: "We are involved in an important protest against the visit of Donald Trump the 45th president of the United States of America.

"He is a racist. His is a bigot. His is an Islamophobe. He is somebody who is misogynistic.

"All of those things together make for somebody who represents deeply an unpopular strain of politics."

Police officers had to gather around some Trump supporters waving a "Scots for Trump" banner.

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.

Protesters will also gather outside the Trump International Golf Links in Balmedie on Saturday, and further demonstrations are expected at Trump Turnberry.

Campaigners were refused permission to fly a 20ft Donald Trump baby blimp over the golf course and plans to bring it to Holyrood on Saturday have also been quashed.

The 20ft inflatable depicting the US president as a nappy-clad baby holding a mobile phone was flown above Parliament Square in London on Friday.

Organisers had planned to transport the blimp to Scotland overnight on the sleeper train and fly it at a protest near the Scottish Parliament on Saturday.

However, a spokeswoman for the Scottish Parliament said: "Parliamentary officials have declined a request to fly the balloon at Holyrood, as it would not be an appropriate use of the Parliament's grounds.

"We do, however, support the right to protest and have agreed to the rally setting off from Holyrood on Saturday."

In an interview with the Sun newspaper published on Thursday night, Mr Trump accused Prime Minister Theresa May of "wrecking Brexit".

He then backtracked on his comments during a joint press conference with May on Friday afternoon, describing the article as "fake news".

During the same Sun interview Trump said he does not "feel welcome" and admitted he was avoiding the city to escape mass protests.

Earlier on Friday evening the President and First Lady Melania Trump met the Queen at Windsor Castle. It followed a state dinner at Blenheim Palace on Thursday.

Trump is expected to golf in Scotland until Sunday afternoon, when he will fly to Helsinki for a meeting with Russian President Vladimir Putin.
