Prince Harry has shown his five-year-old son footage of his late mother, Princess Diana, walking through a minefield.
The Duke of Sussex is currently at the Invictus Games - the competition he founded for injured, sick and wounded military personnel and veterans - in Canada and told how a conversation with his eldest child, Prince Archie, about the devastating impact of landmines led to an unexpected chat about his beloved mother and her famous walk in Angola in 1997.
