This was said to be one of Queen Elizabeth II's favourite tiaras, which she frequently wore throughout her reign.

The diadem was gifted to the late Queen by her grandmother, Queen Mary, as a wedding gift in 1947.

Camilla additionally accessorised with the late Queen's diamond necklace and earrings tonight.

King Charles has upheld the tradition that the new monarch visits the City of London in their Coronation year.

His Majesty was presented with The Pearl Sword tonight, which is thought to have been presented to the City of London by Queen Elizabeth I in 1571.

The ceremony was performed by Queen Elizabeth II in 1953 and during her Jubilees in 1977 and 2002.

Inside, Charles and Camilla had the opportunity to view the Anointing Screen, which was gifted by the City of London Corporation and City Livery Companies for the Coronation, which took place in May.

They met those involved in the screen’s creation, including its designer Aidan Hart and members of the Royal School of Needlework and the Worshipful Company of Weavers.

The King and Queen then joined a reception where they met representatives of the City of London Corporation, the Common Council, the Livery Companies and the City’s finance sector, before signing the visitor’s book.

Charles and Camilla later went into the Egyptian Hall for dinner where the Senior Grecian of Christ’s Hospital School, Zaphaneth Puplampu, gave a Loyal Address.

This is traditionally given during the first official visit of the sovereign to the City of London.

The Lord Mayor made a Speech of Welcome before King Charles gave a Speech of Reply.
