1 Mar 2021 A member of the British government’s scientific advisory panel has implied that the prime minister’s timetable for lifting lockdown could be set back if Britons take advantage of any rare warm Spring weather and undertake allegedly risky business such as going to the beach or meeting up with friends. Professor Calum Semple, who sits on the Scientific Advisory Group for Emergencies (SAGE), said people gathering represented a “big worry” for his colleagues and the government, claiming it could undo the progress made by Britons spending a year under lockdown. “Really, we do urge people to take care. We’re just not quite there on the road map — we can’t take a short cut with people’s health,” Professor Semple told Sky News on Sunday.
