Doe anyone seriously believe that Ed Balls is capable of adhering to such a policy? Ed Balls, the great deficit creator. Ed Balls, the deficit denier. Ed Balls, the man who did more to destroy the British economy than anyone in the last Labour government (other than Gordon Brown) of course.
In any sane society Ed Balls' promise to balance the UK's books would be greeted with hysterical laughter and total derision. However I'm sure the BBC will treat Ed Balls' pronouncements as gospel and question him ever so gently.
