Data on when coronavirus lockdown restrictions can start to be eased will be assessed before mid-February, the prime minister has said.
Boris Johnson said the government will be "looking at the potential of relaxing some measures" before the middle of next month.

Exhausted medics fight to keep patients alive at the Royal Free Hospital in London – but many never make it home.
Speaking at a COVID-19 vaccination site at Barnet Football Club in north London, the PM said: "We're looking at the data as it comes in, we're looking at the rates of infection, as you know the JCVI [Joint Committee on Vaccination and Immunisation] groups 1 to 4 [on the priority list] will be vaccinated by February 15.
"Before then we'll be looking at the potential of relaxing some measures.
"But don't forget this country has made huge progress in reducing infection, I don't think people want to see another big surge in infection."
A Number 10 source told Sky News the PM meant the "looking at" restrictions will happen before the middle of next month, not the relaxing of measures.
Health Secretary Matt Hancock said at the weekend that any easing was a "long, long way" off.
Mr Johnson also said ministers were "definitely looking at" requiring travellers arriving into the UK to quarantine in hotels.

Matt Hancock says everyone must observe the rules on COVID restrictions to help bring case numbers down.
He said: "We have to realise there is at least the theoretical risk of a new variant that is a vaccine-busting variant coming in, we've got to be able to keep that under control."
Mr Johnson added: "We want to make sure that we protect our population, protect this country against reinfection from abroad.
"That idea of looking at hotels is certainly one thing we're actively now working on.
"We need a solution that gives us the maximum possible protection against reinfection from abroad."
The PM declined to guarantee that all pupils will be back at school before Easter, but promised to tell parents and teachers "as much as we can as soon as we can".
"Daily we're looking at the data and trying to work out when we're going to be able to lift restrictions," he said.
"Schools obviously will be a priority but I don't think anybody would want to see the restrictions lifted so quickly while the rate of infection is still very high so as to lead to another great spread of infection."
