Further changes to England’s tier system are expected to be announced on Wednesday, just days after millions of people came under harsher coronavirus restrictions on Boxing Day.

Matt Hancock is due to address the Commons on Wednesday afternoon, with more areas set to move into the lockdown-like Tier 4 due to rising case rates around the country.

Here is a summary of the Covid-19 tier levels ahead of Mr Hancock’s update.
