Scottish minister Russell says Scots vote will 'have to be negotiated'

Scottish government minister Mike Russell has said a date for a second independence referendum "will have to be negotiated".

He was speaking after Prime Minister Theresa May refused to be drawn on whether she believed in the "principle" of a fresh vote.

The focus on Scotland's constitution comes on the day the UK government formally began the Brexit process.

Mrs May has insisted "now is not the time" for an independence referendum.
