The Duke and Duchess of Sussex have paid tribute to Princess Diana and her revolutionary charity work in honour of Pride Month.

Taking to their official Instagram account, the royal couple posted a collage of touching to raise awareness of organisations which support the LGBTQ+ community such as the Human Rights Campaign, akt and The Trevor Project.

'Continuing with our tradition to rotate the accounts we follow based on causes and social issues that matter to us: For the month of June we 'proudly' shine a light on PRIDE,' the caption reads.

'This month we pay tribute to the accounts supporting the LGBTQ+ community - those young and old, their families and friends, accounts that reflect on the past and are hopeful for a deservedly more inclusive future,' the couple continued. 'We stand with you and support you. Because it’s very simple: love is love.'

But Prince Harry also made sure to include a famous photograph of his mother, Princess Diana, meeting one of the patients at Aids hospice London Lighthouse.

The historic image was taken in October 1996, less than a year before her death, and demonstrates how the late royal used her global platform to challenge the social stigma surrounding HIV and Aids.

Most famously, Princess Diana opened the UK's first HIV unit at London Middlesex Hospital.

Whilst in front of the cameras, she shook hands with patients without wearing gloves - a subtle gesture challenging the widespread belief that the disease can be spread on through touch.

Princess Diana famously shook hands with patients on the Aids ward at Middlesex Hospital in April 1987

'HIV does not make people dangerous to know, so you can shake their hands and give them a hug,' she said at the Children and Aids Conference in April 1991. 'Heaven knows they need it.'

Prince Harry has since gone on to follow in his mother's footsteps.

In 2016, the royal travelled to Barbados to take a HIV test with singer Rihanna. While one of the Duke and Duchess of Sussex's first joint royal engagements was a visit to the Terrence Higgins Trust World Aids Day charity fair in November 2017.

The Duke and Duchess of Sussex are certainly carving their own royal path and have pledged to make LGBTQ+ rights a priority.

'Both Prince Harry and Miss Markle said they would put LGBT issues at the front of their work,' LGBTQ activist, Jonah Chinga, said in April 2018.
