The day of Britain’s vote to decide its future with the European Union, will also be marked by another unusual event: the arrival of Donald Trump in the United Kingdom.

The presumptive Republican nominee, who has said if he were British he “would be inclined to leave" the EU, will touch down in Scotland, just as the ballots of the historic decision are being counted.

And in a further departure from convention, Mr Trump will not use this first visit since becoming a presidential candidate to glad-hand political leaders of America's closest ally.
