SIR – The first week of Cop26 has seen hundreds of private jets, Tesla cars recharged by diesel generators, the obscene emissions of Joe Biden’s entourage, India stating it will take 50 years to reach net zero, and China not even present – and all for the sake of some unenforceable pledges.

SIR – An old friend of ours has been in hospital for two weeks. He has had regular Covid tests, all negative, but he has just been pinged by Test and Trace telling him that he has been in contact with someone who has Covid and must self-isolate for 10 days.
He isn’t certain if he’ll be out of hospital by then.

SIR – Huge numbers of people have to isolate after being pinged by the NHS Covid-19 app, crippling the economy in the process. Why on earth can these people not go to work, if they test negative every day, as the Prime Minister tried to do himself?
