Coronavirus: Hancock warns 'it's not over yet' as London heads for tier 3 - BBC News
Health Secretary Matt Hancock warns people to be vigilant as London is set to move into tier three.
The next question comes from the BBC's Vicki Young, who asks whether the government reckons it should be rethinking plans to relax rules over Christmas?

From 23-27 December rules are being relaxed to allow three households to mix.

Mr Hancock says it's "important" that all of us are cautious and "very careful" over Christmas.

But he says that "especially after a difficult year", he understands why people want to get together with their loved ones.

Prof Chris Whitty is also asked what he thinks of the Christmas rules, and says "it's no secret... Christmas is a period of greater risk".

But he says they have tried to strike the balance of doing what is "least damaging" while keeping the virus under control.

And he urged people to take the tiers seriously before Christmas to reduce the risk as much as possible. "Go no further than you have to," he said, of the relaxation in rules.

Prof Kevin Fenton, Public Health England's regional director for London, said "the actions we take now" will affect our ability to have a safe Christmas.

"The restrictions in the tiers will still be in place. But the Christmas period allows us to meet those who are nearest and dearest to us but also taking care to prevent the transmission to them as well."
