If you followed the professional money in the markets you'd soon discover out of all the countries on the planet, the UK is the least trusted, with the US 2nd.....why? Well one reason is the massive debt they've both run up that will take at least a decade to pay off. While countries that done NOTHING, which is the correct way.....strangely have no extra debt, and are coming out of recession!!!
When Cameron said do nothing, that was the correct thing to do, as any professional in the money markets would tell you.
