LONDON (Reuters) - The UK Supreme Court begins two days of hearings on Tuesday to consider whether the Scottish government can pass legislation allowing it to hold a second independence referendum without the approval of the British government.

In a referendum in 2014, Scots voted 55%-45% to remain in the United Kingdom, but nationalists argue that the vote for Brexit two year later changed everything.
