Charles will be officially proclaimed as King at a meeting of the Accession Council, attended by his son Prince William, on Saturday.

For the first time ever, the event will be shown on TV.

The council, due to take place from 10am, is also attended by invited Privy Councillors, serving government ministers, and could also include former ministers and prime ministers.

The King will attend the second part of the meeting to make a declaration and sign an oath to uphold the security of the Church of Scotland and the continuity of government.

In a sign of how historic institutions modernised during Queen Elizabeth II’s reign, the Privy Council website has advised councillors to check their emails for an invitation to the Accession Council meeting.

Following the meeting, the Principal Proclamation announcing Charles as sovereign will be read at 11am from the balcony overlooking Friary Court at St James’s Palace, central London.

The proclamation will be read an hour later at the Royal Exchange in the City of London, and then at midday on Sunday in Scotland, Northern Ireland and Wales.
