The postcode checker revealed which areas would face the toughest restrictions in Tier 3 – including Manchester City, Leeds and Wolverhampton.
Health Secretary Matt Hancock said in a written ministerial statement: “Thanks to the shared sacrifice of everyone in recent weeks, in following the national restrictions, we have been able to start to bring the virus back under control and slow its growth, easing some of the pressure on the NHS.
“We will do this by returning to a regional tiered approach, saving the toughest measures for the parts of the country where prevalence remains too high.
“The tiering approach provides a framework that, if used firmly, should prevent the need to introduce stricter national measures.”
He added: “We must all dig deep, the end is in sight.”
