What the papers say is still seen by many who don’t buy them | Brief letters

Newsstand influence | Tax relief for charitable giving | Starter for 10 | Mind-body dualism | A period of silence from MPs

Archie Bland notes the declining circulation of the Sun and the Times (Winning over the Times and the Sun won't decide the next election - but Starmer's Labour can't kick the habit, 2 April). But newspaper displays in supermarkets and motorway service areas act as billboards. Thousands of non-buyers still see the screaming tabloid headlines every day. Whether they are influenced would be an interesting research topic.

Incentives to donate to charities already exist (Letters, 2 April). Tax relief at the donor's highest rate of up to 45% is given for each pound donated. Rather, we need incentives for the government to close the loopholes that let the very rich treat income tax as optional.
