Supreme court to rule on second Scottish independence referendum

Decision should settle whether Scottish parliament can hold independence poll without Westminster approval

• What could the supreme court say in the ruling?

The supreme court will rule on Wednesday morning whether the Scottish parliament can hold a second referendum on independence without Westminster approval, as pro-independence supporters are expected to take to the streets in rallies across the country.

The ruling will have significant political repercussions for both the UK and Scottish governments depending on how it falls. It may finally settle the process question that has vexed both sides of the constitutional debate since the Scottish National party lost the first independence referendum in 2014.
