What is alert level 4?
Wales will enter alert level 4 from 28 December, the most similar level of restrictions to the first lockdown or the firebreak in the autumn.
However, unlike then, schools and childcare will stay open.
People will be required to stay at home, not create an extended household and only mix with their household or support bubble.
A support bubble can be formed by single adults or single parents joining another household.
The rule on who you can mix with applies both indoors and outdoors.
Travelling will only by allowed for essential purposes, such as for work and for caring responsibilities. International travel would not be allowed.
All indoor and outdoor events and visitor attractions will be cancelled or closed, non-essential shops will shut as will gyms, hairdressers, hospitality businesses and holiday accommodation.
Wedding ceremonies and funerals can take place with limited numbers, but no receptions or wakes can occur.
