Leeds is likely to face new coronavirus lockdown restrictions from midnight tonight to tackle rising infection rates across the city.
City council leader, Tom Riordan, said he expects a ban on households mixing to be introduced, however the measures haven't yet been agreed by the government.
Speaking at a virtual news conference, Mr Riordan said the council wanted to let people know what was likely to happen.
He said: “What we are trying to do is give a simple message – you shouldn’t really mix with other households.
“I think we know from the experience of Leicester, Greater Manchester and West Yorkshire that when these restrictions are brought in they do not tend to be lifted after a week or two.”
The council chief said about 780,000 people will come under the new measures which could be in place through the winter.
Councillor Judith Blake also said she expected Leeds will be made an “area of intervention”, meaning “more household restrictions along the lines of those already in force across three of the West Yorkshire districts in Bradford, Kirkless and Calderdale”.
Leeds director of public health, Victoria Eaton, said the city’s virus rate was 98.5 per 100,000 people with a positive testing rate of 8.4 per cent.
She said: “The spread of the virus is very dynamic across the city.

“It’s clear to see we have very widespread community transmissions right across the city.
“We have high rates in some of our student areas which we have increased more recently.
“It’s clearly not just an issue for student areas.”
She said cases were rising in all age groups, not just young adults, and that compliance with self-isolation rules was still low in Leeds.
“We want to find ways to support local people to isolate,” Ms Eaton added.
“The expectation is the restrictions will be in place for a longer period of time, potentially right through the winter.”
The addition of Leeds’ 793,000 population would take the number of people living under local restrictions to more than 16.2 million people across the UK.
Meanwhile, London is being made an “area of concern”, according to London Councils, a cross-party organisation which represents all 32 boroughs and the City of London.
No additional measures will be taken in the city but testing capacity will be boosted to closely monitor the growth of the virus.
In a statement, London Councils urged residents to follow the new government restrictions introduced on Thursday and said rising cases were a “stark reminder that now is time for all Londoners to pull together and take action to keep themselves, their families and their communities safe, and to ensure that London’s economy is protected”.
It added: “London boroughs are working with their communities, business and the police to engage, educate, explain and, if necessary, enforce the new restrictions and regulations, and the Government must ensure that it funds these so resources do not need to be drawn from other services.
“We ask all Londoners to work together and abide by the national restrictions announced on Tuesday.”
