The royal brothers have reportedly commissioned two TV programmes to mark the 20th anniversary of their mother's death, after the Princess was tragically killed in a car crash in Paris, France, in 1997.

According to the Daily Express newspaper, William, 34, and 32-year-old Harry will pay personal tributes to their mother in the documentaries which are set to be aired by the BBC and ITV in the UK later this year, where they will also share their memories of the days immediately following Diana's death and the national outpouring of grief.

A royal source told the publication: "The Duke and Prince Harry have selected close friends and family members to speak about Diana and some will be speaking about her publicly for the first time."

The ITV documentary, which is set to air in July, will focus on Diana's legacy and achievements with her charity work, whilst the BBC film - which is scheduled for August - will look back at the national and global reaction to her death.

Meanwhile, Prince Harry - who was just 12 years old at the time of Diana's passing - recently gave an impassioned speech about his mother when he continued her work protesting against the use of land mines at a conference in aid of International Mine Awareness Day last week.

Before making his speech, Harry introduced two men - named Malic and Žarko - to the audience, and revealed they had both met Princess Diana as young boys after they both lost legs to land mines in Bosnia.

Prince Harry said in his speech: "She shared their stories with the world, and helped campaigners - many of whom are in this room - to change history.

"Those two young boys, Malic and Žarko, are now grown men and are with us today. 20 years on, they both still struggle with their physical and emotional injuries and with the high costs of replacing their prosthetics.

"When my mother said goodbye to Žarko that August, just weeks before her untimely death, she told him he would not be forgotten.

"Please help me keep her word to Žarko and Malic, and other people like them throughout the world, who still need us to finish the job and rid the planet of landmines.

"Collectively we have the knowledge, skill, and resources to achieve it, so let's make future generations proud."
