Boris Johnson is reported to be considering a near-complete lockdown of parts of the UK in an attempt to get the coronavirus under control.
17.8 million people currently live in the north of England, South Wales, the Midlands and parts of Scotland under some form of lockdown.
And the whole country has a ban on gatherings of more than six people while the restaurants have to close at 10 p.m.
It is now reported that the government is considering tougher measures that would close all pubs, restaurants and bars for at least two weeks.
Households are also not allowed to mix indoors.
The move comes after the new measures announced last week, some of which go into effect today and which also urged people to work from home whenever possible.
Areas of the difficult new lockdown include the North East, North West and London.
Schools and shops are allowed to stay open, as are factories and offices where employees cannot work from home, the Times added, citing a high-level government source.
Thousands of university students are currently isolating themselves in their rooms after rising cases like Glasgow, Manchester Metropolitan and Edinburgh Napier.
An estimated 17.8 million people – more than a quarter of the UK population – will be facing stricter coronavirus restrictions as of late Sunday as new measures were put in place in Cardiff and Swansea from 6 p.m.
The Welsh government also announced that Neath Port Talbot, Torfaen and the Glamorgan Valley will be closed on site from 6pm on Monday.
The government said there had been an additional 5,693 laboratory-confirmed cases of coronavirus in the UK as of 9:00 a.m. on Sunday.
Another 17 people had died within 28 days of testing positive for Covid-19 on Sunday.
