Christmas Day as fears over the Omicron Covid-19 variant grow, an expert has warned. Cambridge University professor Sir David Spiegelhalter has made the worrying claim as Covid cases have risen in 60% of areas in the UK in just a week.It also comes at the same time that London was revealed to be the least vaccinated area in the entire country.The new variant threatens to ruin festive plans for households up and down Britain for the second year running.
Sir David told BBC Newsnight on Wednesday: “I haven't seen the sums behind it, it sounds like it is in fact possible.“It depends on whether people get tested, because more than half of people who are infected don't go on and get tested.
