A second independence referendum. When and how could Scotland vote again?

Summary:

The Scottish government is demanding a second independence referendum, but the UK prime minister, Boris Johnson, has ruled out giving consent for one.

This paper considers when and how such a vote might take place and the factors that would make it seem more – or less – legitimate.
