PMQS: Cameron and Roy on Scotland currency and debt

Labour MP Lindsay Roy asked the prime minister about a "reckless approach" of an independent Scotland potentially not paying its share of the UK national debt if it was not allowed to keep sterling.

David Cameron said a Scottish government defaulting on its debts would was "one of the most chilling things" said in the campaign, and it would lead to higher mortgages and crippling interest rates for businesses.
