Boris Johnson is to lead a coronavirus press conference in Downing Street on Tuesday evening.
The prime minister will be joined by England’s chief medical officer Prof Chris Whitty and NHS England chief executive Sir Simon Stevens. It will take place at 5pm.
It comes as passengers arriving in England from high-risk coronavirus hotspots look set to be made to quarantine in hotels to limit the spread of new variants – though it’s not known if an announcement will be made at Tuesday’s press conference.
Johnson was set to discuss the proposals, designed to ensure people follow self-isolation rules, with senior ministers at the “COVID Operations” committee on Tuesday.

Home secretary Priti Patel earlier declined to comment on “speculation” about quarantine hotels as she answered an urgent question in the Commons.
Reports have suggested arrivals in England would have to cover the price of quarantining in hotels for 10 days, potentially setting them back more than £1,000.
The BBC said the requirement to isolate in a hotel would apply to arrivals from most of southern Africa and South America, as well as Portugal.
