Watch: Scottish Greens co-leaders leaving Bute House
Scottish Greens co-leaders Lorna Slater and Patrick Harvie have been seen leaving Bute House amid speculation on the future of the Scottish government power-sharing deal.
Scotland's first minister Humza Yousaf has called an emergency meeting of his cabinet later.
Ministers usually meet on a Tuesday but have been called to Bute House for the second time this week.
The BBC understands that the SNP would form a minority government if its agreement with the Greens ends.
The Greens co-leaders were questioned by BBC Scotland News political reporter Darren McCullins as they left the first minister's official residence in Edinburgh.
