Donald Trump has left for the US after a whirlwind four-day trip to Scotland.The president mixed business with pleasure in the "private visit", agreeing a major trade deal and meeting the UK and Scottish heads of government in between rounds of golf.

Before his 2016 election, President Trump correctly predicted that the forces animating Brexit would go beyond the United Kingdom. But now most Britons say Brexit was a mistake.

Protestors in Scotland say they will mount a wave of resistance as US President Donald Trump arrived in the country on Friday for a five-day private visit.
