Re the delay in banning new petrol cars (Report, 20 September), is there any reason why car manufacturers cannot carry on with their plans to be all-electric by 2030? I don’t think there can be an obligation on a manufacturer to produce particular goods in a market economy, so if they stop producing petrol cars, we won’t be able to buy them.

• Can you please stop referring to the “Truss era” (Junking green policies, junking investment: scorched-earth Conservatism is all Sunak offers now, 22 September). The word “era” describes a long period of time, when Liz Truss had the briefest of tenures as prime minister. The more accurate phrase is the “Truss error”.
