Under the new measures, areas in England are classified at medium, high or very high risk, and placed under restrictions of varying severity.
Areas in the lowest tier will follow existing national restrictions, including a 10 p.m. curfew on pubs and restaurants and a ban on more than six people gathering. In areas at high risk, members of different households are barred from meeting indoors.
The “very high” risk tier will face restrictions including closing pubs — apart from those that serve meals — and, if local authorities want, other venues such as gyms and casinos.
Liverpool was the only area put into the top category Monday, but Johnson said authorities were still talking with other local leaders across the north of England.
Pubs, gyms, leisure centers, betting shops and casinos in Liverpool will close beginning Wednesday.
Liverpool Mayor Joe Anderson said local authorities supported tougher restrictions as long as they were accompanied by improved test-and-trace measures to suppress clusters of infections — something he said the government had agreed to.
“As well as protecting lives and doing things to tackle the virus, we also need to protect livelihoods, so we argued really strongly for a stronger financial package,” said Anderson, a member of the opposition Labour Party. “Unfortunately, that wasn’t listened to.”
