It seems only a few years ago that the BBC would hang on every word of Vince Cable as an economic guru of great stature. In reality he was a pygmy amongst giants barely more credible than the others on the left (e.g. Ed Balls and the Economics section of his PPE degree).
But last week Cable gave an interview to the Grauniad that appears to have passed the BBC's collective notice. Not surprising really, because what did the now-government minister say? That the rate of spending under the last government was unsustainable, that we would all have to tighten our belts and that GDP might drop several per cent as a result. I could have told him that a couple of years ago.
In fact I did.
