Stricter lockdown measures have been announced in Leicester because of a rise in coronavirus cases in the city.
Health Secretary Matt Hancock said non-essential shops will shut on Tuesday, and schools will close for most pupils on Thursday.
The loosening of restrictions for pubs and restaurants in England on Saturday will also not be taking place.
Mr Hancock said Leicester accounted for "10% of all positive cases in the country over the past week".
He told the House of Commons on Monday evening: "We recommend to people in Leicester, stay at home as much as you can, and we recommend against all but essential travel to, from and within Leicester."
The secretary of state added the new local measures would be in place for at least two weeks, but kept under constant review, and "we will not keep them in place any longer than is necessary".
Mr Hancock said the number of positive coronavirus cases in Leicester was "three times higher than the next highest city", and the relaxation of shielding measures on 6 July – which will allow the most clinical-vulnerable to spend more time outside – will also not take place in Leicester.
He said the decision to close non-essential retail was based on clinical advice, and added that "children had been particularly impacted" by the local outbreak and the risk of Covid-19 being transmitted by children is the reason why schools will be closed.
"To be clear, children have very, very low risk of suffering from Covid themselves but we have been looking at the proportion of children who have tested positive and therefore may be transmitting the disease," he said.
Five Leicester schools have closed since the beginning of June because of the number of coronavirus cases and the wider closures from Thursday will affect most pupils, but children of "critical workers" and those classed as vulnerable will still be able to attend.
Suburbs of Leicester, such as Oadby, Birstall and Glenfield, will also be affected, but Mr Hancock said details of the wards in Leicestershire covered by the new lockdown measures would be published "imminently".
Leicester City Council said the new "stricter lockdown restrictions" would be in place for "at least two weeks", and it was working to establish which other parts of Leicestershire would be affected.
The authority said in a statement: "The latest figures obtained by the city council show that 3,216 Covid-19 cases have been confirmed in Leicester since the start of the epidemic. Of these, 944 cases were reported in the last two weeks.
"These figures include the number of patients and staff testing as positive in hospitals… and positive cases identified in testing centres."
Mayor of Leicester Sir Peter Soulsby said the measures imposed by the government were "stricter than we anticipated but we understand the need for firm action".
He said: "[The government] are clearly determined to start with the maximum, as it were, to see how it works and then perhaps to use the learning from this in other areas I have no doubt will follow.
"I can understand it from [the government's] perspective – they are entirely convinced that the level of the transmission of the disease in Leicester is at a higher level than I think the figures show."
Leicestershire County Council leader Nick Rushton said "protecting residents is our main concern" and added it "makes sense to step up restrictions in areas closer to the city".
"I understand this is disappointing news for residents, parents of schoolchildren and businesses when most of the country is opening back up but it's crucial that people follow the latest advice.
"Observing social distancing, hand-washing, wearing a face mask where required and getting tested if you have symptoms remain vital."
Mr Hancock said the government had also "agreed further measures" to tackle the Leicester outbreak:
- A walk-in test centre will be opened in the city, alongside mobile testing units
- The city and county councils will be given "extra funding" to enhance communications to the population on Covid-19 in all relevant languages
- Councils will ensure "support is available to those who have to self-isolate"
- Workplaces that have seen "clusters of cases" will be helped to implement stringent Covid-19 guidance
He added the Government is "still getting to the bottom of" the potential reasons why the outbreak in Leicester has occurred.
Blake Edwards, owner of Flappers and Gentlemen salon, said he was "devastated" by the news.
The Leicester hairdresser was supposed to reopen on Saturday but will now remain closed "with no new date in sight".
He said: "It's going to be really tough for the clients too.
"Time is running out [for the business now], we're going to need more support.
"Even though the staff is being furloughed, rent still needs to be paid, all the other bills still need to be paid.
"We don't know what the next 12 months are going to be like."
Leicester's Highcross shopping centre tweeted on Monday evening that "only essential retail stores", alongside "restaurants and cafes offering takeaway or delivery" services, would open on Tuesday.
Rakesh Parmar, who owns Ye Olde Sweet Shoppe in the city centre, said the further restrictions will affect him "financially very, very badly".
He said: "The impact of coronavirus hit us on March 23rd, we closed for 10 weeks, and then opened again on June 15 – it's been one long slog."
Mr Parmar said he "completely" understood why a further lockdown would be needed, but asked how his customers were feeling he said: "Very, very scared because it's closer to home than we realised."
If there is one thing that has become clear during the pandemic, it is that the quicker action is taken the better.
Given the scale of the outbreak in Leicester that has emerged, it therefore comes as no surprise that the government is taking tough action.
But the question that is being asked behind the scenes is whether it took too long to spot the scale of the outbreak.
One of the concerns about the test and trace system is how quickly data gets passed from the national team to local officials.
The national team passes on plenty of cases – any complex cases involved care homes, schools and prisons are automatically transferred.
But what local authorities are not getting quickly are comprehensive details about individuals who test positive.
