Boris Johnson yesterday insisted four weeks of lockdown should be enough to drive down cases and return to a tiered approach.
Speaking during a Downing Street press conference, the Prime Minister said: “The advice I have received suggests that four weeks is enough for these measures to make a real impact.
“These rules will expire and on December 2 we plan to move back to a tiered approach.
“There is light at the end of the tunnel.
“These are difficult times. While it pains me to have to ask once again for so many to give up so much, I know we can get through this.”
Mr Johnson insisted “the objective” is to return to regional restrictions next month so “people across this country will be able to have as normal a Christmas as possible”.
YouGov polled 1,658 British adults on October 28 to 29.
