In January 1997 the world’s most famous woman, Diana Princess of Wales, called for an international ban on landmines.
She was visiting Angola where she caught global attention by walking through a live minefield.
Her trip is credited with boosting the campaign for a global landmine treaty signed later that year.
Paul Heslop accompanied Princess Diana during her walk across the minefield.
