Boris Johnson calls for 'extreme caution' over Christmas

British Prime Minister Boris Johnson is calling for extreme caution over Christmas - urging people to hold smaller gatherings to control the spread of the coronavirus. The government is facing pressure from medical experts to tighten restrictions over fears the relaxation could trigger another severe spike in cases. The prime minister has refused to reverse his decision and has asked people to consider their plans carefully. “We are collectively across the UK, governments at every level, asking you to think hard and in detail about the days ahead,” Mr Johnson said. “A smaller Christmas is going to be a safer Christmas, and a shorter Christmas is a safer Christmas.”
