Dozens of ministerial posts may remain unfilled despite end of Queen’s mourning period

King Charles announced further royal mourning period – and appointments are made by the monarch

Dozens of ministerial posts may remain vacant for another 10 days despite the mourning period ending after the Queen’s funeral on Monday, Downing Street has admitted.

The problem has emerged because King Charles has announced a further week-long royal mourning period – and ministerial appointments are made, officially, by the monarch.

The prime minister’s office is now scrambling to work out if it is able to fill the posts – put at 55 by one count, which No 10 disputes – next week or be forced to wait until the following week.

Asked when the posts will be filled, a No 10 spokesperson said: “We will update on the next steps as soon as we can”.

Officially, Liz Truss’s reshuffle is “paused”, although Zac Goldsmith revealed he has been sacked from his environment brief, while remaining a Foreign Office minister.

Meanwhile, the new prime minister is preparing for a blizzard of behind-the-scenes diplomacy ahead of the funeral, meeting six world leaders over the weekend.

As expected, she will hold talks with Joe Biden, as well as the leaders of Ireland, Australia, New Zealand, Canada and Poland – but not France or Germany.

It is thought that a first meeting with Emmanuel Macron – who has made clear his hopes of healing UK-French relations, with the departure of Boris Johnson – will take place in New York next week.

On Saturday, Ms Truss will meet Anthony Albanese, the prime minister of Australia, and Jacinda Ardern, his counterpart in New Zealand, at the Chevening country residence.

On Sunday, she will meet Irish taoiseach Micheal Martin, Canada’s prime minister Justin Trudeau, the Polish president Andrzej Duda and Mr Biden, the US president, in Downing Street.

China’s official delegation has been barred from attending the Queen’s lying in state ahead of the state funeral – after its controversial invitation to the funeral itself.

Lindsay Hoyle, the Commons speaker, has prevented them entering Westminster Hall because seven MPs and peers who have attacked China’s “genocide” of Uighur Muslims remain sanctioned by Beijing.
