In a hugely significant statement, the Queen’s message was also acknowledged by Archbishop of Canterbury Justin Welby, head of the Church of England, who said: “I warmly welcome Her Majesty’s wish that HRH The Duchess of Cornwall will take on the title of Queen Consort when, in the fullness of time, HRH The Prince of Wales becomes King.”

He added: “Along with the rest of the Church of England, and millions more around the world, I pray for Her Majesty, for Prince Charles and the Duchess of Cornwall, and for all the Royal Family.”

In 2005, there was deep controversy within the Church about the suitability of a church wedding for the Prince and the then-Camilla Parker-Bowles: both of whom were divorced, and had admitted an adulterous relationship.

In the event, the couple had a civil ceremony, followed by a blessing at St George’s Chapel at Windsor Castle, with “prayer and dedication” led by Dr Rowan Williams.
