Senior ministers will gather before a special session of Parliament where peers and MPs will share their memories of the Queen.
To honor the Queen, Liz Truss’ cabinet gathered in Downing Street.
A number of senior ministers, many of whom were only appointed this week, including Business Secretary Jacob Rees-Mogg and Education Secretary Kit Malthouse, were seen arriving for the gathering.
“Cabinet was united in their support for His Majesty the King, as he and the United Kingdom continue to mourn the passing of his mother. There was a moment of silence at the conclusion of the meeting.”
The gathering comes before a special session of Parliament, starting at midday, in which MPs and peers will share their memories and praise for the monarch, who died at Balmoral on Thursday aged 96.
Ms Truss became the Queen’s 15th prime minister when she was appointed at Balmoral on Tuesday.
The meeting became the last public appearance of the monarch.
Later on Friday, Ms Truss will meet the King when he returns to London from Scotland, where he had been since the Queen’s health deteriorated.
