British Prime Minister Boris Johnson said on Thursday there was light at the end of the tunnel on COVID-19 as England entered its second countrywide lockdown - for four weeks - to prevent a rising number of cases and deaths from the virus. “The UK government and the devolved administrations are working together on a joint approach to the Christmas period, because all of us want to ensure families can come together, wherever they live,” he told a media conference. “The advice I’ve received suggests that four weeks is enough for these measures to make a real impact so these rules will expire. There is light at the end of the tunnel.”
