Thursday August 31,2017 Twenty years since Diana died in a car crash in Paris, triggering a flood of public grief. Princes William and Harry honored their mother Wednesday at Kensington Palace, her former home, visiting a garden where she would stroll by and ask the gardeners about their ever-changing displays. The princes and the Duchess of Cambridge met with well-wishers after the walk, but aren't expected to take part in any engagements today
