A vote to leave the EU would cost the Scottish economy £4.5bn, the Chancellor will warn.

On a visit to Scotland, George Osborne set out analysis which he argues shows the size of Scotland's economy would be reduced by £4.5bn if the UK left the European Union.

The Chancellor also argued leaving the EU will increase the number of those unemployed in Scotland by a total of 43,000. by 2018.

Osborne said: "Every credible independent voice agrees that if the UK votes to leave the EU there would be a profound economic shock that would hurt people's jobs, livelihoods and living standards in Scotland.

"Trade exports to the EU have created jobs in Scotland and withdrawing from the single market would have a huge impact on the economy here.

"It is simply not a price worth paying. I urge everyone to vote to remain in the EU on 23 June."

Osborne was also joined on his visit to Scotland by Scottish Conservative leader Ruth Davidson.

Davidson argued "thousands" of jobs in Scotland are "reliant" on being a member of the European Union.

She said: "The big question facing us on June 23 is what is best for jobs and for family security - leaving the EU, or staying part of the single market.

"There's no question in my mind that staying part of the EU is the right answer.

"Thousands of Scottish jobs re reliant on the export we sell within the EU. I'll be voting to remain in order to ensure we can create thousands more over the coming years".

The Chancellor's intervention into the debate in Scotland was blasted by former Labour MP Tom Harris, who is heading the Vote Leave campaign in Scotland.

He called Osborne's figures "made up"and it was a "desperate attempt"to "scare voters" to back Remain on referendum.

Harris said: "The people of Scotland won't take kindly to the Tory austerity chancellor coming to Scotland in a desperate attempt to scare voters into backing remain. Osborne and Cameron know the only jobs under threat from leaving the EU are their own.

"His made up statistics have been dismissed by supporters of his own side as scaremongering, and it's about time the Chancellor stopped talking down Scotland and the UK's economy."
