"Intensity Six." Sitting in The Golden Lion pub in Barnard Castle today nursing a pint of Hobgoblin. Idly watching silent BBC News coverage of the current Labour squabble about alleged anti-Semitism. Sub-titles referred to Intensity Six. Uh? Is that to do with seismic stuff? Or more like Captain Kirk's Warp Factor Nine? Then all became clear. Ken Livingstone was apparently asking whether it was right to say England had been invaded by the Normans. "Intensity Six". The item was followed by more sub-titles about severe wider in the North of England tonight, with a risk of heavy slow. Only one pint, honest.
