King Charles III ruled that only working members of the royal family will be able to stand in for him if he is abroad or ill, it has been reported
Currently, the Counsellors of State include the spouse of the Monarch and the next four people in the line of succession over the age of 21..
This means disgraced Prince Andrew and Duke of Sussex Prince Harry are able to step up for the King.
It is the latest shake-up in the King's reign as he makes changes to who will stand in as Counsellors of State to "ensure continued efficiency of public business when I am unavailable".
Before the new rule, the current Counsellors of the State were Queen Camilla, Prince William, Prince Harry, Prince Andrew and Princess Beatrice.
Counsellors of State can be called on to stand in for the Monarch should they fall ill or be absent from duties.
Under the proposed changes, the Duke of York, Harry, Meghan Markle and Princess Beatrice will not be able to get called up.
On Monday night, the House of Lords debated plans for two extra "Counsellors of State" including adding Princess Anne and Prince Edward to the list.
The Bill will add Princess Royal and the Earl of Wessex to the list, but stops short of removing Andrew and Harry.
However, the House of Lords heard that only "working members" of the royal family would be called upon to act as Counsellors of State.
Speaking at the Bill's second reading, Lord Janvrin, an independent crossbencher, said: "The present pool of working members of the royal family who are eligible and available to be counsellors of state is for reasons which are well known very small.
"The addition of the Earl of Wessex and the Princess Royal makes very good practical sense.
"If I can, when many minds are on football, it will give much-needed strength and depth to the bench."
A Labour peer argued that Harry and Andrew should be taken off the list as non-working royals.
The Counsellors of State Bill being argued tonight also saw peers debate adding two royals to the last rather than removing any of the current stand-ins.
The Bill received a second reading and it is planned to complete its remaining stages on Wednesday before heading to the Commons.
Buckingham Palace told The Mirror they would not comment on these matters.
