Prime Minister Boris Johnson announced that England will enter a new lockdown to curb rising coronavirus cases.
The new restrictions come into place on Tuesday 5 January, following fears that the four-tier local system was not enough to contain the new, more transmissible strain of the virus.
People will be legally required to “stay at home”, and schools will close to most pupils while the restrictions are in place.
However, the children of critical workers can still go to school, meaning their parents can continue to go to work during the pandemic.
So, who does the government deem to be key workers during England’s third lockdown? Here is the full list.
