Prime Minister says Covid restrictions could get tougher to keep virus under control
Mr Johnson signalled current anti-Covid measures were likely to get tougher, saying: "What we are doing now is using the tiering system, which is a very tough system... and, alas, probably about to get tougher to keep things under control.
"But, we will review it."
He added: "And we have the prospect of vaccines coming down the track in their tens of millions.
"And that, I think, is something that should keep people going in what I predicted, back on your show in in October, will be a very bumpy period right now.
"It is bumpy and it's going to be bumpy."

It comes as ex-Prime Minister Tony Blair has said that the entire country needs to be placed under a Covid-19 vaccination programme.
The former Prime Minister told Times Radio: “Because of this new variant, we need to change our strategy completely in my view.
“And the paper we published today shows how we can get up to three million, I think we could get up to three million a week by the end of January, provided that the vaccines are available, and they should be.
“Not only Pfizer and AstraZeneca but possibly with the new Johnson & Johnson vaccine as well coming on stream.
“We should be aiming to get up to three, four, five million a week.
“We need to get the entire country under a vaccination programme very, very fast because right now as a result of this new variant, we’ve got a choice between severe lockdown or vaccination.
“But there isn’t another choice.
“If I was the Prime Minister right now I would be saying to the team in Downing Street, ‘I need you to give me a plan to get this up to five million (vaccinations) a week’."
