Opposition leaders have urged ministers to rule out the use of a Scottish Government-owned airport for Donald Trump's visit.

The US president is expected due to arrive in Scotland on Friday evening, and is believed to be spending the weekend playing golf at his Turnberry resort in South Ayrshire.

Flying restrictions have been put in place around the resort and nearby Glasgow Prestwick Airport, which was bought by Scottish ministers in 2013.

Scottish Greens co-convener Patrick Harvie and Scottish Labour leader Richard Leonard and said the publicly owned facility should not be available to Trump.

In a joint statement, they said: "Donald Trump is not welcome here. The horrific scenes at the Mexican border are a repudiation of decent human values.

"Caging children like animals is barbaric. We cannot roll out the red carpet for a US president that treats human beings this way.

"From his disgraceful equating of anti-fascist campaigners with Nazis in Charlottesville, his withdrawal from the Paris Climate Agreement, to his Islamophobic travel ban and his misogyny Donald Trump has demonstrated that he should be denied any kind of welcome."

The statement continued: "Scotland can and should work for peace and co-operation in the world. To this end we believe that all avenues must be used to ensure that Donald Trump does not receive a welcome here.

"For Donald Trump to travel to Scotland with public assistance and ease when his travel ban has caused outrage and despair around the world would simply not be acceptable.

"We urge that the Scottish Government rules out any use of Prestwick by the president or his entourage, and so send the most powerful message possible that Donald Trump is not welcome in Scotland."

The Scottish Government said ministers do not intervene on how the airport is run.

A spokesman said: "Prestwick Airport is operated on a commercial basis and at arm's length from the Scottish Government, in compliance with EU state aid rules.

"Ministers do not intervene in any specific commercial matters at the airport.

"Scotland has deep and longstanding ties of family, friendship and business with the United States, which will continue to endure.

"At the same time, we will not compromise our fundamental values of equality, diversity and human rights, and we expect these values to be made clear during the presidential visit to the UK."
