"The prospect of Scotland voting next week Yes to independence and turning away from 400 years of history fills me with despair, frankly," Niall Ferguson, the Scottish-born professor of History at Harvard University, who has talked of renouncing his U.K. passport if there is a Yes vote, told CNBC.
"Their [the nationalists'] story is simply economic fiction. Their story is that somehow you can keep the pound while leaving the United Kingdom. That's false. Their story is that somehow or other they can increase welfare spending, even as they cut themselves off from revenues from the obviously richest part of the U.K., the south-east of England. And finally their story is that somehow the oil is going to increase in volume when all experts in the energy industry will tell you that North Sea oil output is dwindling. So it is economic fiction, and yes it is disturbing that nearly half of Scots appear not to get that," he argued.
