Sweden's controversial decision not to impose a strict lockdown in response to the Covid-19 pandemic led to too many deaths, the man behind the policy, Anders Tegnell, has acknowledged.
Sweden has seen a far higher mortality rate than its nearest neighbours and its nationals are being barred from crossing their borders.
Dr Tegnell told Swedish radio more should have been done early on.
"There is quite obviously a potential for improvement in what we have done."
Sweden has counted 4,542 deaths and 40,803 infections in a population of 10 million, while Denmark, Norway and Finland have imposed lockdowns and seen far lower rates.
Denmark has seen 580 deaths, Norway has had 237 deaths and Finland 321. Sweden reported a further 74 deaths on Wednesday.
