The Government has warned that a mutant new strain of Covid-19 is “out of control” and in danger of spreading from the South East of England across the country.
Over a thousand cases have already been identified - with the number expected to soar much higher despite tough new Tier 4 restrictions and the Government tearing up its rules for Christmas.
Here we look at the new variant - VUI-202012/01 - and how much of a threat it poses. Why does it spread so quickly? Scientists believe the new strain of the virus is more contagious than others because of a mutation on the spike protein which helps the virus latch onto human cells.
