Breaking – Nicola Sturgeon resigns as Scotland’s FM 

Nicola Sturgeon is to resign as Scotland’s first minister after more than eight years in the role.

The SNP leader is expected to make the announcement at a hastily-arranged news conference in Edinburgh.

It is not clear exactly when she will leave office.

Ms Sturgeon has been first minister since November 2014, when she took over from Alex Salmond following the independence referendum.

She went on to become the country’s longest-serving first minister.

This is a breaking story.
