Live COVID updates as lockdown begins
People are once again being told to stay home, apart from for a limited number of exceptions.
A surge in cases is being driven by a new variant of coronavirus that has been judged to be between 50% and 70% more transmissible.
As of Monday, there were 26,626 COVID patients in hospital in England – an increase of over 30% in one week and now more than 40% higher than the peak of the first wave of infections last April.
There has also been a near 25% increase in the number of deaths in the past seven days, compared to the previous week.
