Caution has been urged ahead of a major easing of England's lockdown, which will allow pubs and restaurants to serve customers outside and hairdressers and non-essential shops to resume business.
Indoor gyms, swimming pools, nail salons and zoos will also reopen tomorrow as lives take another step back towards normality.
However, social mixing indoors will remain heavily restricted, with around 40% of adults yet to receive their first dose of a Covid-19 vaccine.
Professor Peter Horby, a senior scientist advising the British government, warned that the remaining rules must be abided by to minimise the effects of a future "rebound" in cases.
