These are the latest coronavirus infection rates for every local authority in England as more cities and towns are set to be moved into Tier 4.
There are 16 places currently in Tiers 2 and 3 that have higher rates than Tier 4 areas, meaning they could be most at risk of facing the toughest restrictions, according to new figures.
Each has a Covid-19 infection rate higher than 300 new cases per 100,000 people, and rates are climbing in all but two of them.
They include Tier 3 areas Burnley and Pendle in Lancashire, Birmingham and Wolverhampton in the West Midlands, Northampton in the East Midlands, and Hartlepool in the North East, and Tier 2 areas Eden and Carlisle in Cumbria.
