The comments from Boris Johnson followed those of his spokesperson, who told reporters: “The over 60s should take extra care because there is evidence they could be at greater risk of becoming seriously ill.
“The scientific advice is that people in the over 60 age group do have a higher risk of becoming more unwell with coronavirus, so they should take extra precaution.”
Advice for the clinically vulnerable previously only applied to those over 70, or with an underlying health condition, but new guidance – which comes into force when England’s lockdown is implemented on Thursday – has been extended to over 60s.
The government says it has hit its target of being able to carry out 500,000 coronavirus tests a day across the UK by the end of October.
The data for 31 October showed just over 525,000 tests could be done – a doubling of capacity in two months.
However, just under 300,000 tests were actually carried out.
Officials said the labs did not work at full capacity as there needed to be flexible to cope with demand surges or staffing and equipment problems.
The target was set by ministers in early summer as part of the expansion of the Test and Trace system.
Universities say students in England should not move home for the lockdown – even if courses are switched to being taught online.
They do not want a rush of students leaving universities as the new restrictions come into force this week.
But the National Union of Students says students should have a choice to go home safely ahead of the lockdown.
The government’s guidance says universities should consider putting teaching online where possible.
Universities UK says students should stay in their current accommodation and a mix of face-to-face and online teaching will continue through the lockdown.
The number of coronavirus infections in Spain rose by 55,019 on Monday, the biggest daily increase since the start of the pandemic and more than double the increase of 25,595 new infections on Friday, health ministry data showed.
The death toll went up by 379, bringing the total number of coronavirus fatalities to 36,257 in Spain, which approved a six-month state of emergency last week to try to curb the second wave of contagion.
The 379 deaths was the sharpest one-day rise of the second wave, though still a far cry from nearly 900 at the peak of the first wave of the virus in late March.
The big jump in infections can partly be explained by the accumulation of cases over a three-day bank holiday weekend in Spain.
The official cumulative number of infections now stands at 1,240,697, but Prime Minister Pedro Sanchez has said the real total is likely above 3 million based on prevalence studies and estimates.
There have been two further coronavirus-related deaths and 767 new cases of the disease notified to the Department of Health In Ireland.
It brings the total national number of cases to 62,750. This includes the denotification of 19 previously confirmed cases. The total number of deaths stands at 1,917.
In total there were 103 Covid-19 related deaths confirmed in October of which 39 were in nursing homes. This compares to 36 deaths in September and five in August.
The national 14-day incidence rate now stands at 248 cases per 100,000. The five-day average is 671 cases per day, confirmed Deputy Chief Medical Officer Heather Burns.
