Liverpool’s Champions League game with Atletico Madrid and racing’s showpiece Cheltenham Festival “caused increased suffering and death” by going ahead in March, a leading scientist told the BBC on Tuesday. Professor Tim Spector, who leads the United Kingdom’s largest Covid-19 tracking project, said rates of cases locally “increased several-fold” following the events. Cheltenham attracted over 250,000 spectators to southwest England on March 10-13 and Liverpool played the Spanish side at Anfield on March 11 in front of a 52,000 crowd.
