LONDON (Reuters) - Britain is at risk of suffering a third wave of coronavirus infections if it does not get the approach to lockdown restrictions right in the coming weeks, foreign minister Dominic Raab said on Sunday. “There’s a risk of that (if) we don’t get the balance right,” Raab told the BBC when asked about a possible ‘third wave’ resurgence of cases in January and February. He said the government was doing everything it could to avoid another national lockdown.
