Scientist warns UK 'on a knife edge' ahead of lockdown easing

Scientists have warned that the country remains "on a knife edge" and should observe "constant vigilance" to prevent a second wave of coronavirus cases as lockdown measures are eased.

Sir Jeremy Farrar, director of the Wellcome Trust, admitted he is "worried" about a possible spike in infections ahead of the reopening of pubs, restaurants and hairdressers next month.

He warned that there could be a "very nasty rebound" of coronavirus in the winter if the UK does not use the next few months "sensibly".

Sir Jeremy, who is also a member of the Government's Scientific Advisory Group for Emergencies (Sage), argued that the next three months were "absolutely critical" in the fight against coronavirus in the UK.

He said: "Come the winter, come the reopening of schools, which is absolutely critical, we can anticipate to see rebounds and second waves."
