Let’s put the Greek problem in its proper perspective. Britain’s Great Depression in the Thirties has become part of our national myth. It was the era of soup kitchens, mass unemployment and the Jarrow March, immortalised in George Orwell’s wonderful novels and still remembered in Labour Party rhetoric.

Yet the fall in national output during the Depression – from peak to trough – was never more than 10 per cent. In Greece, gross domestic product is already down about 13 per cent since 2008, and according to experts is likely to fall a further 7 per cent by the end of this year. In other words, by this Christmas, Greece’s depression will have been twice as deep as the infamous economic catastrophe that struck Britain 80 years ago.
