Alistair Darling is learning the lessons that previous Labour Chancellors have learned, namely that careless talk costs the pound dear.
Sterling continued on its downward path today, falling to a 12 year low (88.2) against the Bank of England trade weighted index of currencies and to its lowest against the dollar ($1.7669) since April 2006.
The fall has been attributed, not unsurprisingly, to Darling's outburst over the weekend over the state of the economy.
The fact that he is now barely on speaking terms with his old "friend" Gordon Brown have given the markets little comfort, as divisions over policy and presentation between number 10 and number 11 mean that the economy will suffer.
Until Brown and Darling decide what the real story is, and what to do about it, the economy will continue to decline.
