This question is very similar to the Plan C question posed by juancambeiro but with an earlier deadline and slightly different criteria to account for the possibility that restrictions may come into place before the end of the year.
On 8 Dec 2021, Boris Johnson confirmed that the UK will move to "Plan B" COVID measures in response to the Omicron variant. These include:
- Face masks to become compulsory in most public indoor venues, other than hospitality
- NHS Covid Pass to be mandatory in specific settings, using a negative test or full vaccination via the NHS Covid Pass
- People asked to work from home if they can
Johnson has indicated that he 'reserves the possibility' of implementing further restrictions after Christmas, such as limiting household mixing, amid surging omicron cases.
[Short-fuse] Will implementation of measures more severe than those in “Plan B” be announced in the UK before 1 January 2022?
This will resolve positively if the UK Government announces, before 1 January 2022, that COVID measures more stringent than those in "Plan B" will be implemented in all of the UK before 1 January 2022. Measures announced before the end of the year but which come into force in January will not result in a positive resolution.
For the purposes of this question, this should include at least two additional measures — for instance, a ban on inter-household mixing and closing of pubs.
