Boris Johnson will address the nation after an emergency cabinet meeting this afternoon amid fears of a third lockdown.
The Prime Minister has come under intense pressure this week over his 'Christmas bubbles' as Covid-19 rates soar in parts of the UK, with the country said to be on a "knife edge".
He will hold a briefing at 4pm today from Downing Street alongside chief medical officer Prof Chris Whitty and chief scientific adviser Sir Patrick Vallance, Number 10 has confirmed.
It follows grim warnings about a new highly-contagious strain of the virus which has sparked speculation that a third national lockdown could be just days away.
Prof Whitty today said urgent work is underway to confirm whether the new strain is more deadly
Ministers met yesterday to decide how the mutant strain, which has ripped through London, Kent and Essex, could be controlled.
Medics warn that the new strain is 50% more contagious than previous Covid-19 cases.
In a statement today Prof Whitty said: "As announced on Monday, the UK has identified a new variant of Covid-19 through Public Health England's genomic surveillance.
"As a result of the rapid spread of the new variant, preliminary modelling data and rapidly rising incidence rates in the South East, the New and Emerging Respiratory Virus Threats Advisory Group (NERVTAG) now consider that the new strain can spread more quickly
