At the castle, Tom Lloyd, the Herald of Arms Extraordinary of Wales, will make the proclamation in English and the Lord Lieutenant of South Glamorgan, Morfudd Meredith, will proclaim King Charles in Welsh.

After the readings, members of the 104th Regiment, Royal Artillery will fire a 21-gun salute before God Save The King and Hen Wlad Fy Nhadau, the Welsh national anthem, are sung.

The flags on the Castle and Council buildings, which were at half-mast, were brought back to full-mast on Saturday to coincide with the reading of the new monarch’s main proclamation in London.

Flags will be returned to half-mast at 1pm on Sunday after the Proclamation has been read in Cardiff.
