Scottish Liberal Democrat leader Willie Rennie has said that the SNP Government must show maturity if it wants the UK to remain in the EU.
It comes after Nicola Sturgeon said she would refuse to work with the Conservatives as she restated her call for each nation in the UK to have a veto over exiting.
Ahead of Nicola Sturgeon's speech in the European Policy Centre, Mr Rennie said:
"People will want the SNP to show maturity and do everything in their position of government to ensure the UK remains in the EU.
"Nicola Sturgeon's talk of a veto and a refusal to work with some political parties is disappointing because it is a distraction from the fundamental premise of this debate - do we want Britain to lead the EU or leave it?
"Scottish Liberal Democrats made a consistently positive case for Scotland to remain in Britain and in Europe because we believe that is the best conditions for jobs and growth. With the majority of Scots in favour of Scotland remaining in the UK, Nicola Sturgeon must accept that and give her full support to efforts to remain in the EU. Otherwise, constant quibbling by the SNP will only be seen as an attempt to sow division between parts of the UK. That will not contribute any good to the case for remaining in the EU."
