Before a special session of Parliament during which MPs and peers will share their recollections of the Queen, the senior ministers will meet.
The cabinet of Liz Truss has gathered in Downing Street to pay tribute to the Queen.
Several top ministers, many of whom were only appointed this week, including Business Secretary Jacob Rees-Mogg and Education Secretary Kit Malthouse, were observed arriving at the event.
A Number 10 spokeswoman said: “At 9.30 a.m., the cabinet paid homage to Her Majesty and reflected on her career of service, including warm memories of their interactions with her.
“Cabinet was unified in its support for His Majesty the King as he and the United Kingdom continued to grieve the loss of his mother. A moment of quiet was observed after the meeting.”
The meeting precedes a special session of Parliament beginning at noon, during which MPs and peers will share their recollections of and appreciation for the monarch, who passed away on Thursday at the age of 96 at Balmoral.
Tuesday at Balmoral, Ms. Truss was appointed as the fifteenth prime minister of the Queen.
The meeting marked the monarch’s final public appearance.
Ms. Truss will meet the King on Friday evening when he returns to London from Scotland, where he has been since the Queen’s deteriorating health.
The audience is anticipated to occur in the middle of the day, however, the time has not yet been confirmed.
This evening, the PM is also expected to attend a memorial ceremony for the Queen at St. Paul’s Cathedral, where he will deliver a reading.
After 48 hours in the office, Ms. Truss stated the steps of Number 10 on Thursday evening, referring to the Queen as “the rock upon which modern Britain was constructed.”
She went on: “She is the reason why Britain is the amazing country it is today. She was the embodiment of the British spirit, and this spirit will survive.”
She also stated that the British people “must unite as a nation” to support the King and “help him shoulder the immense burden he now bears for us all.
Ms. Truss concluded her remarks with the phrase, “God save the King.”
On Friday morning, the shadow cabinet also met, with Labour leader Sir Keir Starmer leading tributes to the Queen and a moment of silence.
After her death was announced, Sir Keir referred to the monarch as a “wonderful monarch” and added: “Above political conflicts, she stood for what the nation agreed upon, not what it fought about.
As our glorious Elizabethan era comes to a close, we shall honor the legacy of the late queen by preserving the public service virtues she exemplified.
Ms. Truss and Sir Keir will likely lead the tributes in the House of Commons, which will continue into Saturday.
