England might see the introduction of further coronavirus restrictions akin to a “tier 5”, a government source has suggested, as experts warn tier 4 might not be enough to shrink the epidemic.
Tier 4 restrictions came into force in London and parts of the south-east and the east of England on 20 December and have since been extended to a large swathe of the country, from Cambridgeshire to Sussex and parts of Hampshire. Under these restrictions, people have been told to stay at home, with household mixing banned outside support bubbles, although one person can meet up with one other person outdoors.
