A new three-tier system of local lockdown measures for England will be announced by the Prime Minister in an effort to curb rising Covid-19 rates.
Different parts of the country will be split up into "medium", "high" or "very high" local coronavirus alert areas under the new system Boris Johnson is expected to announce on Monday.
It comes after the Prime Minister held a telephone conference with Cabinet colleagues on Sunday to discuss the situation and ongoing negotiations with local leaders in the north of England.
The PA news agency looks at some of the questions surrounding the incoming system.
- What do the tiers mean?
The three tiers represent an advancing scale of local restrictions.
Tier one restrictions are thought to be the baseline restrictions in place across England, including a 10pm hospitality curfew and a ban on most gatherings of more than six people.
Tier two restrictions are expected to be similar to rules currently in place in Middlesbrough and parts of the North East, where indoor mixing of households is not allowed.

Many details are yet to be confirmed but leaders in Liverpool said pubs and bars, betting shops, casinos, and gyms will close under the third, "very high", tier restrictions, while reports also suggest people will have to avoid all non-essential travel and to not travel between areas.
- Which areas may be placed into tier three?
It is not yet clear how an area will be placed into a tier, or to what extent regulations will be written and enforced locally.
However, a statement from leaders across the Liverpool City Region confirmed Liverpool, Wirral, Knowsley, Sefton, St Helens and Halton will be subject to tough Tier 3 coronavirus lockdown restrictions
This will see pubs, bars, gyms, betting shops, casinos, and adult gaming centres close.
Nottingham continues to have the highest rate in England, with 2,763 new cases recorded in the seven days to October 8 - the equivalent of 830.0 cases per 100,000 people.
- What happens next?
Many of the details of how the tiers and the specific measures in each area will be negotiated and enforced are currently unclear.
On Monday, the Prime Minister will chair a meeting of the Government's COBR committee to finalise what will be announced in Parliament.
He will later host a press conference at Downing Street where he will be joined by Chancellor Rishi Sunak and England's chief medical officer Professor Chris Whitty.
Downing Street said MPs would be asked to debate and vote on the three-tier measures next week.
Steve Rotheram, metro mayor of the Liverpool City Region, said his priority was to secure a support package for businesses affected by the new restrictions.
He told BBC Radio 4's Today programme: "We are told that the order will be placed before Parliament today, there will be some debate tomorrow, but that the orders are likely to be enacted on Wednesday.
"What we are trying to do is to see whether we can get support and the support package for the businesses in our city region that will be affected by the Government's decision."
Mr Rotheram said there is little they can do to challenge the decision.
"We were told we were going into Tier 3, no ifs, no buts. We can either expend energy on that or we can try and get a better deal," he said.
"Some people like to shout at the wind but if they can't change the direction of the wind it is important to shield people from its effects."
