The Sun quotes insiders saying Boris Johnson will bring forward his update on the Omicron variant from the original 18 December date to reassure the nation about plans for Christmas.
The newspaper says ministers are worried the public will lose trust if they have to make another last-minute change to Christmas celebrations and will break the cycle of three-week updates to reassure the country.
The announcement will centre on the Christmas break but looks certain to include mention of the latest travel restrictions.
