Scottish televsion historian Neil Oliver has called the prospect of a second independence referendum a "cancerous presence".

He came out in favour of a no vote during last year's referendum campaign, and in a interview with the Sunday Times today he says talk of a second vote is creating uncertainty

Oliver said: "Now that there is talk of a second referendum, my problem with it is over the continued uncertainty.

"I thought it would be put to bed on September 19, 2014 - but it hasn't been.

"I think any uncertainty for any reason is a cancerous presence. I'm aware of it.

"People around us are not sure what to do.

"Do they invest in Scotland? Do they buy a house in Scotland? Do they start a business un Scotland? All the things that seemed unclear during the referendum are still unclear."

Neil says he received death threats during the referedum campaign last year and was told he should be "burnt alive."
