Mr Hancock added: “Infection rates are also rising sharply in Barrow-in-Furness, in York, in North East Derbyshire, in Erewash and Chesterfield.
“In all of these places, cases are doubling in less than a fortnight.
“For all of the areas entering the high alert level, the change will come into effect one minute past midnight on Saturday morning and this includes Barrow-in-Furness, York, North East Derbyshire, Erewash and Chesterfield too.”
London is also entering into Tier 2 lockdown from Saturday.
