If the list of most watched TV programmes on Christmas Day tells us anything, it’s surely that if a particular programme is made hard to avoid by running it on all the most popular TV channels (and GB News), it’s probably going to get the biggest audience. Not that nearly 7 million people actually chose to watch it (King Charles’s annual message is most watched TV show in UK on Christmas Day, 26 December).

• My favourite examples of the Merlin bird app making mistakes (Report, 27 December) are when it identified the peacocks at my local arboretum as ospreys, and when a siren went past on a nearby road and the app confidently told me it was a peregrine falcon.
