The result of the United Kingdom's referendum on its continued membership of the European Union has caused a constitutional crisis that has reignited calls for Scottish independence.

June's plebiscite on EU membership saw 53 percent of the English electorate vote for Brexit. While in Scotland nearly two thirds chose "remain."

The next step should be simple. As Scotland's internationally acclaimed author Irvine Welsh tweeted: "People shouldn't have any problem with Scotland staying in Europe or England leaving. It's what they voted for. It's called democracy."
