The Prime Minister delayed the meeting to sign off his long term plan for living with Covid until later today.
The exact reasoning behind the sudden postponement remains unclear, with even senior Cabinet ministers left in the dark.
One No10 source told Express.co.uk that the meeting was delayed while Mr Johnson received an update on the unfolding situation in Ukraine, but others say an explosive row over the Covid plan has broken out between Chancellor Rishi Sunak and Health Secretary Sajid Javid.
The insider told this website: “A lot going on, as you know, so Cabinet has been delayed whilst the PM is briefed on the latest developments re the Ukraine.
They added Cabinet “will be convened later to sign off on the living with Covid strategy”.
However, a source told The Sun there were still frictions over the Covid plan that needed fixing.
They told the publication: “Some issues needed ironing out between Department of Health, Treasury and No10.”
