Prince Charles has said he is “deeply conscious of the honour represented by my mother’s wish” for his “darling” wife to be known as Queen Camilla.

It comes after the long-serving monarch used the historic milestone of her Platinum Jubilee to express her “sincere wish” that the Duchess of Cornwall will be known as queen consort when the Prince of Wales is crowned king.

The royal seal of approval on the 70th anniversary of the Queen’s reign represented a significant intervention in shaping the future of the monarchy.

It publicly put the sovereign’s affairs in order in the twilight of her rule and ends years of controversy over Camilla’s future title.

In a statement, Charles said: “On this historic day, my wife and I join you all in congratulating Her Majesty the Queen on the remarkable achievement of serving this nation, the Realms and Commonwealth for 70 years.

“The Queen’s devotion to the welfare of all her people inspires still greater admiration with each passing year.

“We are deeply conscious of the honour represented by my mother’s wish.

“As we have sought together to serve and support Her Majesty and the people of our communities, my darling wife has been my own steadfast support throughout.

“The year of this unprecedented Platinum Jubilee brings an opportunity for us all to come together in celebrating the service of the Queen, by whose example we will continue to be led in the years to come.”

When Prince Charles married Camilla in 2005, royal aides insisted that Camilla did not want to be queen and said originally that the former Mrs Parker Bowles “intended” to be known instead as princess consort, the first in British history, instead.

It was seen at the time as an acknowledgment that the public was finding it difficult to accept Charles’ new wife, after their affair and his divorce from Princess Diana.

Technically, Camilla would have been Queen when Charles acceded to the throne, and only legislation would have prevented it.

But the Queen has now closed the matter in a move seen to help to make the start of her son’s reign as trouble free as possible.

In her message to the nation to mark Accession Day, and the start of her Jubilee year, the Queen thanked people for their support during her reign.

She wrote: “I remain eternally grateful for, and humbled by, the loyalty and affection that you continue to give me.

“And when, in the fullness of time, my son Charles becomes king, I know you will give him and his wife Camilla the same support that you have given me; and it is my sincere wish that, when that time comes, Camilla will be known as queen consort as she continues her own loyal service.”
