UK - The world economy is at risk of another financial meltdown, following the failure of governments and regulators to push through all the reforms needed to protect the system from reckless behaviour, the International Monetary Fund has warned. With global debt levels well above those at the time of the last crash in 2008, the risk remains that unregulated parts of the financial system could trigger a global panic, the Washington-based lender of last resort said. The former UK prime minister Gordon Brown said last month that the world economy was “sleepwalking into a future crisis,” and risks were not being tackled now “we are in a leaderless world”.
