On 4th January 2021, Prime Minister Boris Johnson announced that England would enter a third national lockdown.
The restrictions include a ban on socially meeting anyone outside your home or 'support bubble' (but allow you to exercise outdoors with one such person).
In the four-tiered system of restrictions in place before the lockdown, it was possible in "tier 1" regions to meet others indoors or outdoors, but only in groups of up to 6 people.
When will most people in England be legally able to meet socially in a group of six in private indoor places?
This question resolves on the earliest date on which the majority of the population of England are legally allowed to meet any five other local people in a private indoor place, such as a house.
By 'any five local people', we mean that the question should not resolve if (say) each person were allowed to pick a fixed 'bubble' of people they are allowed to meet with. But the question should resolve positively even if mixing is not allowed with people from certain other regions.
To be precise, the question should resolve when the majority of people in England could truthfully say "There are at least 10,000 people I could legally arrange to meet inside my home today in a group of six, if I could contact them and they agreed."
