Bank of England Governor Mervyn King, who has always shown a fondness for the odd weather-related metaphor, is on excellent  form as he warns of the Eurozone’s “black cloud of uncertainty”.

Let’s have some numbers for a change, Merv!

Those ever-closing isobars of debt will doubtless soon result in a maelstrom of further borrowing and Quantitative Easing.
