Being Queen Consort one day will not stop the Duchess of Cornwall campaigning for the causes she believes in, she has vowed.

The Duchess, speaking in an interview at Clarence House, suggested that the Queen’s confirmation of her future title had already boosted her charity campaigns, elevating her platform.

Saying that the monarch’s personal support for her future title of Queen Consort was a “great honour”, she pledged to “keep up” with issues such as domestic violence for “a lifetime”.

On Thursday, she will call on schools to teach “respect” to help prevent violence against women, and stop offenders “treating women like chattels and people thinking they can get away with it”.

Earlier this month, on celebrating 70 years on the throne, the Queen asked the British public and the Commonwealth to welcome the Duchess as “Queen Consort” when the time comes for the Prince of Wales to be King.

“It is my sincere wish that, when that time comes, Camilla will be known as Queen Consort as she continues her own loyal service,” she said.

The Duchess has now given an interview to BBC Radio 4’s Woman’s Hour and BBC One’s Breakfast show, acknowledging the gesture and suggesting it had already helped give a bigger platform for her work campaigning against domestic violence.

“Of course, it’s a great honour,” she said. “It couldn’t be anything else. But it does help it.”
