The government has added the Midlands, the North East, parts of the North West and parts of the South West of England to the toughest Tier 4 coronavirus restrictions.
It now means 44 million people in England (or 78% of the population) are under the strictest rules.
The changes will take place from New Year's Eve, at 00:01 Thursday 31 December.
