Scottish leader Nicola Sturgeon is due to outline her plans for a new referendum on independence from the U.K.

The first minister is scheduled to update the Scottish Parliament in Edinburgh Wednesday on "Brexit and Scotland's future." Her office did not say whether Sturgeon will set a date for a new vote.

Scots voted against independence by 55% to 45% in a 2014 referendum billed as a once-in-generation poll.

In 2016, the U.K. as a whole voted to leave the European Union, but Scotland voted strongly to remain.

Sturgeon, who leads the pro-independence Scottish National Party, argues that Brexit changes everything because Scotland should not be taken out of the EU against its will.

A referendum would need approval from the British government, which says the time is not right.
