THE former chairman of Yes Scotland has called for a second independence referendum but admitted leaving the UK could see the creation of a "hard border" between Scotland and England.

Dennis Canavan said the case for independence had been "strengthened" by the UK's decision to leave the EU against the wishes of most Scots.

He said Scotland would become more attractive to inward investors if it remained in the EU but insisted: "The only way that could be achieved is if Scotland becomes independent.

"That's why I say, a second referendum on independence, bring it on."

Mr Canavan repeated his backing for a separate Scottish currency, a position he held in 2014, but added: "In the longer term we might want to consider joining the eurozone."

Asked about the prospect of a "hard border" between an independent Scotland in the EU and a UK outside the Brussels bloc, he told BBC Radio 4's Today programme: "I don't want to see a hard border between Scotland and England."

Pressed on whether it would be a price worth paying to retain Scotland's membership of the EU, he said: "Well, you'll have a hard border between Northern Ireland and the Republic of Ireland and there will be a hard border between the UK and the rest of Europe, or at least the rest of the EU.

"The Brexiteers should have thought all this out beforehand.

"I'm not one for creating unnecessary borders but I'm very much in favour of us being members of the European family and international community."

The former Labour MP and Independent MSP's firm backing for a second referendum goes beyond commitments made by First Minister Nicola Sturgeon.

She has said she will exhaust diplomatic efforts to maintain Scotland's relationship with the EU before calling a referendum as a "last resort".

She has also indicated she would prefer to keep the pound rather than join the euro.

Mr Canavan's call also put him at odds with another veteran Nationalist, former SNP leader Gordon Wilson, who argued against a referendum in the near future, unless there was clear and sustained support for independence.

In a strategy paper issued under the banner of his Options for Scotland think tank, he said the SNP should not aim to hold a second plebiscite within the next five years.

He also said the SNP should show greater "humility" than it did fighting the 2014 campaign.
