Sir Martin Donnelly, once Liam Fox's chief civil servant, has described leaving the EU as "like swapping a three-course meal for crisps." Fox is not impressed, dismissing Donnelly for sticking to the patterns of the past. and what does the future look like, in Fox's view? "Confidence, optimism and vision will always deliver more than pessimism or self-doubt." Whether or not that's true, Fox would have benefitted from attending an Arvon writing course, which would have taught him that a snappy concerete image will always beat a string of abstract nouns.
