Health leaders have called for some Covid restrictions to be reintroduced immediately to avoid England stumbling into a winter crisis. They said a back-up strategy, a Plan B which includes mandatory face coverings in crowded and enclosed spaces, should be implemented. UK cases have been rising sharply. Business secretary Kwasi Kwarteng said it was not yet time for a Plan B and urged a greater uptake of booster jabs. He did not want to jeopardise the ‘hard-won gains’ of reopening the economy even though for a week daily Covid cases have averaged above 40,000, the worst figures since March. Overall, he said, ‘the health service is right at the edge’. Meanwhile, the health secretary is telling the public to ‘play their part and get a booster jab’ in order to enjoy Christmas with loved ones. Cabinet Office officials are already discussing ‘Plan C’ proposals which would ban mixing between households. See
