Your list of Channel 4’s 40 best shows (2 November) describes A Very British Coup as “Alan Plater’s conspiracy thriller”. While it is true that Alan Plater wrote a brilliant script, the television series was based on a novel I published in 1982, six years earlier.

• It is a good idea not to buy things you don’t really need just to get points on your loyalty card (Adrian Chiles, 3 November), but some supermarkets’ cards are worth keeping. For example, with Tesco and Sainsbury’s you can donate your points or vouchers to charity, so you are doing your bit without really noticing.
