From the Guardian:
Tier 4' lockdown measures expected in SE England
Molly Blackall
Boris Johnson is expected to introduce tier 4 restrictions for London and the south-east of England in his press conference this afternoon, with the planned relaxation of regulations over Christmas scaled back for the rest of the country, writes Molly Blackall.
Tier 4 restrictions may spell an end to Christmas plans, with those living under the new top tier thought to be prevented from meeting other households over the holiday.
There are also suggestions that just two households will now be able to meet in the rest of England, rather than the planned three.
The prime minister will be joined by the chief medical officer for England, Chris Whitty, and the UK’s chief scientific adviser, Patrick Vallance, for a press conference at 4pm on Saturday, following an emergency meeting with cabinet ministers at 1pm.
It comes as cases of coronavirus surge, and concerns grow over a new strain of coronavirus which is spreading rapidly across the south-east of England.
