Scottish Secretary David Mundell has appeared to rule out the possibility of Scotland having different post-Brexit immigration rules than the rest of the UK.
Securing control of the UK's borders will be one of the Government's main negotiating aims as it looks to formalise its divorce from Brussels.
Stuart C McDonald, SNP MP for Cumbernauld, Kilsyth and Kirkintilloch East, urged Mr Mundell to consider allowing Scotland to operate under a different set of immigration rules for EU nationals.

Mr Mundell said he would consider all "evidence-based proposals" but stressed that immigration remains a reserved power.
Mr McDonald asked during Scotland questions in the Commons: "We know around 180,000 EU nationals make a hugely valuable contribution to the Scottish economy.
"We also know that countries like Canada and Australia successfully apply different immigration rules to different parts of their countries.
"Going beyond warm words, will the Secretary of State listen carefully to proposals for a different arrangement for Scotland, allowing EU citizens freedom to continue coming to live and work there, benefiting us all?"
Mr Mundell replied: "I will always look at evidence-based proposals that come forward and that's our commitment for example in relation to the Scottish Government's paper produced just before Christmas.
"But it was quite clear within the settlement agreed in the Smith Commission that immigration would remain a reserved power."
