The prime minister has said lockdown measures are “starting to show signs of some effect”, but he has refused to rule out extra restrictions in England.
Boris Johnson said measures were kept under “constant review” after Labour leader Sir Keir Starmer said it was obvious more restrictions were needed.
Mr Johnson added that vaccine centres would move to 24-7 “as soon as we can”.
Under the national lockdown, people in England must stay at home and only go out for limited reasons.
This includes for food shopping, exercise, or work if they cannot do so from home. Similar measures are in place across much of Scotland, Wales and Northern Ireland.
