The political historian claimed that this was the first time it had happened in recorded British constitutional history that one monarch finished off the task of another sovereign in approving the next government
A historian has claimed that it is the first time in British history that one sovereign approved the appointments of the Cabinet ministers only to be sworn in by the next monarch.
Dr Nigel Fletcher claimed that it was a "constitutional first" for two monarchs to approve the new cabinet of the UK Government chosen by the Prime Minister.
Dr Fletcher, a political historian at King's College in London, took to Twitter claiming that the Queen approved the appointment of the new cabinet before her death on Thursday that led to the cancellation of a Privy Council meeting.

He claims the meeting was to officially swear in the next cabinet that she had approved after she had asked Liz Truss, her fifteenth Prime Minister, to form a government.
King Charles III held a Privy Council meeting on Tuesday night where he sworn in the next cabinet.
Dr Fletcher tweeted: "A week after the late Queen approved the appointment of Her new Cabinet, The King last night held a Privy Council to formally swear them into their new offices and give them the Seals of Office. A constitutional first: appointed by one Sovereign, sworn in by the next.
"This was the Privy Council meeting that Her late Majesty was due to hold last Wednesday night, which was postponed on the advice of Her doctors. The law requires them to be sworn in, and it was somewhat unclear if their appointments were fully effective until they had been."

He adds: "Ministers, like other offices under the Crown, are not required to be re-appointed by the new Sovereign, since the enactment of the Demise of the Crown Act 1901. Last night’s proceedings were necessitated by the new Government, not the new Reign.
"A notable absence last night was the Prime Minister, who will still need to be sworn as First Lord of the Treasury."
