British Prime Minister David Cameron on Wednesday begged Scots not to rip apart the United Kingdom’s “family of nations”, flying to Scotland to man the barricades against a surge in support for independence eight days before a referendum. Cameron appealed to Scots to use their heads and their hearts when they voted on Sept. 18. He reminded them of their shared history and bonds with England, Wales and Northern Ireland – twice evoking World War Two and the fight against Hitler. He also warned that an independent Scotland could not keep the pound currency, jobs would head south, and the country’s security be weakened. “I would be heartbroken if this family of nations was torn apart,” said Cameron.
