Sir, – Of all the commentary on passports, surely the most benign was Kevin Ryan's prediction that the inner pages of the potential new blue UK document "won't be used as a device to dog-whistle the population into a very narrow definition of what it is and means to be British" (December 30th). Indeed. Why bother, when the cover is what it will be judged by? – Yours, etc,
