London CNN  — 

Britain’s Queen Elizabeth II has used the historic milestone of her Platinum Jubilee to redefine the future of the monarchy, calling for the Duchess of Cornwall to be known as Queen Camilla when Charles becomes King.

When Charles married Camilla in 2005, the couple announced she intended to be known as “Princess Consort” despite having a right to the title of Queen. It was seen as a recognition of the sensitivities around a title that was destined for Charles’ first wife, Diana.

It’s the same reason Camilla doesn’t use the title of Princess of Wales.

The Queen would be expected to consult her direct heirs Charles and William before making such a significant announcement about titles, which suggests they both agreed and felt the British public is ready to accept Camilla as Queen.

The 95-year-old monarch laid out her vision for institution’s transition in an extraordinary message released as she reached the 70th anniversary of her accession to the throne.

“I would like to express my thanks to you all for your support. I remain eternally grateful for, and humbled by, the loyalty and affection that you continue to give me,” the Queen said.

“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.”
