Government officials and local authorities could bring in more restrictions including a Tier 4 if the three-tier system in England has not made a difference to the spread of Covid-19.
The alternative plan would consist of a “Tier 3 plus” or “Tier 4” including shutting restaurants and non-essential retail such as clothes shops.
The measures have not been officially announced or decided but are reportedly being discussed, reports MirrorOnline.
Other options reportedly being discussed include the possibility of short-term local circuit breaker lockdowns to bring the R rate of transmission below one.
Since October 12, England has been operating under a three-tier system of local restrictions which divides areas into different categories, labelled as medium, also known as Tier 1, high, also known as Tier 2, or very high risk, which is referred to as Tier 3.
Areas classed as medium risk, those in Tier 1, are subject to the same national measures that were commonplace across England earlier this year.
These include the 10pm curfew for pubs and restaurants and a ban on most gatherings of more than six people.
Areas categorised as high risk – Tier 2 – have restrictions on household mixing indoors while the rule of six continues to apply outdoors. These apply to Birmingham and much of the West Midlands.
People must not meet socially with friends and family indoors in any setting unless they live with them or have formed a support bubble with them.
People living in Tier 3 areas are advised against overnight stays in other parts of the UK and should avoid travel where possible in and out of the area, unless it is for work, education or caring responsibilities.
In these areas, social mixing is banned both indoors and in private gardens, while pubs and bars must close unless they can operate as a restaurant.
The rule of six applies in some outdoor settings such as parks, public gardens and sports courts.
The UK has recorded another 174 coronavirus deaths and 23,012 more cases in the latest 24-hour period.
The total number of infections in the country is 854,010, while the total number of fatalities is 44,745.
