"Mainstream media headlines today are focused on Britain's record national debt, which just surpassed £1 trillion, a figure that can only exponentially increase unless the entire mechanism of Government finance is overhauled. The truth however is much worse, factoring in all liabilities including state and public sector pensions, the real national debt is closer to £4.8 trillion, some £78,000 for every person in the UK."
