Sweden's light-touch approach to Covid-19 has come under renewed criticism after emails show the country's chief epidemiologist appearing to ask whether a higher death rate among older people might be acceptable if it led to faster herd immunity.

Speculation about the views of Sweden's leading public health officials was further fanned after it also emerged that Anders Tegnell, the architect of the country's no-lockdown strategy, had deleted some of his emails.
