Strict limits will be placed on the number of people who can meet - a maximum of two guests aged 13 and over will be allowed in people's homes, and four on 24-26 December and on New Year's Eve and New Year's Day.
This sounds pretty unenforceable though to be honest.
That seems unecessarily excessive, but in the face of a surge combined with a short deadline (expires Jan 9th) I would be hard pressed to write that down in the history books as and authoritarian atrocity.
