A second national lockdown could be needed if the latest coronavirus restrictions do not work, the foreign secretary has told Sky News.
Speaking to Kay Burley, Dominic Raab said "we can't rule it out", but stressed the government will "take every effort to avoid that".
- Office workers should work from home again if they can
- From Thursday, all pubs, bars and restaurants must only offer table service, and close at 10pm
- All retail staff, people using taxis and everyone using hospitality services must wear face coverings – with fines rising to at least £200 for non-compliance
- Weddings may only include 15 people, while funerals can host up 30
- The "rule of six" has been extended to indoor sports teams
In a televised address to the nation on Tuesday night, the PM urged Britons to "summon the discipline and the resolve" to avoid a second national lockdown after warning there have been "too many breaches" of the rules.
Asked about the prospect of another national shutdown, Mr Raab told Sky News: "We've always said we've got a sort of repository of measures in the arsenal to take.
"I don't think we would speculate about what further could be done.
More from Covid-19
"But the reality is they will be more intrusive or we could end up in a national lockdown.
"That is what we want to avoid."
The foreign secretary described the government's approach as "focused, balanced and proportionate".
And he defended the 10pm curfew for hospitality, after it was put to him that just 5% of cases in recent figures were linked to pubs, bars and restaurants.
"We know that in bars and restaurants, particularly after people have had a few drinks, as you go into the later hours of the evening, that there's a risk that the compliance with the guidance ebbs a little bit," Mr Raab said.
"So we're taking this measure, we're confident based on the evidence that we've got domestically and internationally that it's one element of those that we need to make."
With Mr Johnson warning that the new rules could be in place for as long as six months, the foreign secretary was asked if the chancellor would be extending the furlough scheme.
Mr Raab said Rishi Sunak was "not minded to have a wholesale extension" – a potential hint that partial extension may be in the offing.
Labour's Rachel Reeves told Sky News the party supported the measures taken by the government.
But the shadow Cabinet Office minister told Kay Burley that Labour wants ministers to "fix" the test, track and trace system to provide more support for businesses and workers, and "local packages of support" for areas badly affected by the virus.
