The 31-year-old royal has touched down in South Africa, where he is due to meet delegates at Aids 2016, a global conference about Aids.

Prince Harry will be joined by Sir Elton John to address the delegates on Thursday (21.07.16) and will host a session which will focus on how the disease affects young people.

Meanwhile, the 'I'm Still Standing' hitmaker previously praised Prince Harry for undergoing a HIV test last week which was broadcast live to the world on Facebook.

He wrote on Instagram: "In 1991, Princess Diana moved a mountain by addressing the stigma surrounding people living with HIV/AIDS. She showed the world we could safely wrap our arms around AIDS patients, by shaking hands with a patient without gloves. We've made huge strides since then in the treatment of the disease.

"People now live long, happy lives with HIV, when the virus is effectively managed with anti-retrovirals. Despite this amazing progress, most people today are still frightened and stigmatised at the notion of taking an HIV test. Today in London, Prince Harry gave that stigma a knock on the head by showing the world how easy and simple it is to take an HIV test. Bravo Prince Harry! Your mother would be so proud of you."

Speaking in the video, which was posted on The Royal Family's Facebook account, he said: "It's normal for me, even though I'm not from this part of London or being the person that I am and the people I am sitting around, I am still here being tested."

Prince Harry's result came back as "HIV non-reactive", which means he is "fine".
