Health Secretary Matt Hancock has today warned there will be tougher action needed to tackle the spread of coronavirus.
Mr Hancock is expected to impose strict new measures in a speech in the Commons today, following a sharp rise in cases and hospital admissions across the country.
This morning, Mr Hancock said the country was facing a "significant challenge", as many brace themselves to be moved up a tier.
He said: "We are facing a very significant challenge in the NHS right now.
"There has been a significant rise in the number of cases - the highest number of cases recorded yesterday, 53,000 cases.
"We are going to have to take further action. I'm going to set that out the House of Commons later today."

Mr Hancock is expected to make his statement at 3pm today.
Prime Minister Boris Johnson chaired a meeting of the Government's Covid-19 Operations committee on Tuesday evening, when changes to the tier system were discussed.
With case rates rising in all regions of England, as well as the number of Covid-19 patients in hospitals, any review is likely to involve areas moving up a tier rather than down.
Areas that may be moved from Tier 3 to Tier 4 due to increasing case rates include parts of the East Midlands, such as Northamptonshire and Leicestershire, as well as all areas of the West Midlands metropolitan county.
Hartlepool in north-east England, along with a handful of areas in Lancashire - Blackburn with Darwen, Burnley, Pendle and Ribble Valley - could also be upgraded from Tier 3 to 4.
The Times also reported that ministers are also considering imposing the country's toughest measures on parts of the south west and Cumbria.
