LONDON (Reuters) - Britain’s health minister Matt Hancock said on Monday a new more infectious coronavirus variant means the government needs to be more cautious in lifting lockdown restrictions. The government said on Friday that the new variant may be 30% more deadly than the original strain. “There is no question the new variant made this fight a whole lot tougher,” Hancock told a press conference. “The critical message is we must be cautious. For all of us, our response must be extra careful.”
