Prince Harry has revealed Meghan Markle is "hugely excited" to be joining him in his Commonwealth work as he paid tribute to the Queen's service to the Family of Nations.
Harry described how the woman he will marry in just over a month would be by his side in his new role as Commonwealth Youth Ambassador, a post bestowed by the institution's head the Queen.
The prince's comments came as he helped open the Youth Forum, which launched the Commonwealth Heads of Government Meeting (Chogm) week, with a speech, and told the young delegates "it is you who are going to change the world".
Earlier he was joined by Prime Minister Theresa May at a roundtable discussion with young leaders, where both expressed their faith in the Family of Nation's youth.
During his speech, Harry got cheers and whoops from the audience when he mentioned his bride-to-be, who will join him on Wednesday at a Commonwealth Youth Forum reception.
The prince said: "In my new role, I will work to support the Queen, my father the Prince of Wales, and my brother William, all of whom know that young people are the answer to the challenges of today.
"I am also incredibly grateful that the woman I am about to marry, Meghan, will be joining me in this work, of which she too is hugely excited to take part in."
The US actress and Harry have already expressed their interest in the Commonwealth and it is widely anticipated they will go on a Commonwealth tour after their May 19 wedding.
Harry said he looked for inspiration for his new role from his grandmother the Queen and he highlighted her famous speech from 1947 where she pledged her life to the Commonwealth.
He said: "On the day of her 21st birthday, the then Princess Elizabeth gave an extraordinary radio address from Cape Town.
"With an eye on the future, and an already unflinching sense of duty, she made a commitment. She said that whether her life be long or short, it would be dedicated to the service of the people of the Commonwealth.
"All of us here today can be grateful that it is a long life the Queen is still enjoying. Her Majesty's commitment has meant that the Commonwealth is a thriving family of nations, a common link between nearly two-and-a-half billion people, and a defender of democracy, justice and peace."
