Five new-never-before-seen photos of the late Diana, Princess of Wales were released to coincide with a new documentary.

The 90-minute documentary, Diana, Our Mother: Her Life and Legacy, which aired on ITV in the UK on Monday, 24 July, celebrate Diana’s life and work 20 years after her tragic death in 1997.

The Duke of Cambridge and Prince Harry share fond memories of their childhood as they look through their mother’s photo album.

Prince Harry described his mother as “one of the naughtiest parents.”

Prince William was born on 21 July 1982 and Prince Harry on 15 September 1984 at St Mary’s Hospital, Paddington, in London.

Diana wanted to ensure her two sons experienced life outside palace walls so she took them on outings to McDonald’s, Disney World and other fun parks to homeless shelters and AIDS clinics.

The Prince and Princess of Wales agreed to separate in 1992, the year which the Queen dubbed her “annus horribilis”. Diana remained at Kensington Palace whilst Prince Charles lived at Highgrove but he moved his office to St James’s Palace.

They shared equal responsibility of raising their two boys who spent most of their time away at boarding schools, Ludgrove and Eton.

After the divorce, the Queen, Prince Charles and Diana agreed that her title would be Diana Princess of Wales.

Diana was tragically killed in a car crash following a high-speed chase in the Place de l’Alma underpass shortly before midnight on 30 August.

Her companion Dodi Fayed and driver Henri Paul died whilst the bodyguard Trevor Rhys-Jones was seriously injured.

She died after two hours of emergency surgery at La Pitie Salpetriere Hospital.

Millions worldwide were shocked by this devastating news with a huge outpouring of grief as mourners laid a huge carpet of flowers outside Kensington Palace.

Prince Charles and Diana’s sisters, Lady Sarah McCorquodale and Lady Jane Fellowes, flew to France to bring her remains home aboard a BAe 146 aircraft.

The Duke of Edinburgh, Prince Charles and Earl Spencer accompanied Prince William and Prince Harry as they walked behind their mother’s coffin.

Her funeral was held in Westminster Abbey on 6 September, with Elton John performing his hit song Candle In The Wind, which was rewritten to pay tribute to Diana.

Diana’s body was taken to her family home at Althorp for burial on the estate away, rather than the local church at Great Brington.

Diana, Our Mother: Her Life and Legacy will air on Seven Network Australia, at 7.00 pm, as part of the Sunday Night programme.
