Lockdown measures in north-east England are to be tightened in a bid to halt the rise in Covid-19 cases.
Health Secretary Matt Hancock said tougher restrictions were being brought in than those imposed a week ago.
He said mixing between households in any indoor setting, which people are currently advised to avoid, will be against the law from Wednesday and enforceable with fines.
The rate of infections in the region is now more than 100 cases per 100,000.
Mr Hancock told the House of Commons that cases in the region had “risen sharply”.
Under the regulations that came into force on 18 September, almost two million people in Newcastle, Northumberland, Gateshead, North Tyneside, South Tyneside, Sunderland, and County Durham were banned from socialising with other people outside of their own households or support bubbles in private homes and gardens.
Restrictions imposed in some parts of England, including the North East, have already made it illegal to mix with other households in their homes or gardens, punishable with fines.
What’s new is to extend the legal ban to all meetings with other households in indoor public venues, such as pubs and restaurants – that’s what will happen from Wednesday in the seven listed areas of the North East.
So to meet someone for a drink or a meal will be in breach of the law. Workplaces won’t be affected.
This is the first time in England since the full lockdown began to be eased in May that such extensive legal sanctions have been imposed.
The Department of Health said the imposition of the measures reflected high and rising rates of infection in the region though they appear to have come as a surprise to local council leaders.
Even as MPs debate whether more oversight of government-imposed restrictions is required, health officials have let it be known that further interventions in Merseyside and some other parts of the North West of England may be imminent.
They were also advised not to socialise with people outside of their household in any public venue, but that was only guidance and not banned under law.
Pubs, restaurants and other hospitality venues also remain limited to table service only and have a 22:00 curfew.
Mr Hancock said: “Unfortunately the number of cases continues to rise sharply.
“We know that a large number of these infections are taking place in indoor settings outside the home. And so, at the request of the local councils with whom we have been working closely, we will introduce legal restrictions on indoor mixing between households in any setting.”
Mr Hancock did not say whether visits to other households for informal childcare – such as grandparents looking after children – will still be permitted under the revised rules.
Newcastle City Council leader Nick Forbes criticised the Health Secretary for the manner in which the announcement was made.
“While we have been in discussions with the Government on potential further restrictions, the Secretary of State has once again stood up and announced changes without telling us he was about to do so,” he said.
“We want to work constructively with the Government but the way these measures are being communicated in headlines and without detail does nothing for public confidence.
“We have demanded clarity on the new restrictions, testing and support for those businesses most affected.”
