Princess Diana's iconic walk through the minefields of Angola for the charity HALO Trust is burned in the minds of many royal fans, but in 2019, Prince Harry recreated his late mother's famous footsteps and did the same in Huambo, Angola. Twenty-seven years later, Prince Harry reflected on how he is carrying on Diana's work while speaking at a special HALO Trust reception on September 23.

“As you know, the work of the HALO Trust in Angola meant a lot to my mother. Carrying on my mother's legacy is a responsibility that I take incredibly seriously,” Harry said at the event.

The reception was held during Harry's solo visit to New York for the UN General Assembly High-Level Week and Climate Week, and was a celebration of Angola's leadership in support of landmine clearance and conservation.

“Since my first visit to Huambo in 2019, my life and the world have undergone many changes. In the last five years, I have become a father for the second time,” Prince Harry said, referring to his daughter, Princess Lilibet.

“And while we don't need children to be involved in the future of our planet, I know my mother would have been horrified to know whose children and grandchildren would be living in a world still infested with landmines,” he continued.

The Duke concluded his speech by praising the work of the HALO Trust and calling on everyone in the audience to “finish the job” and clear away the landmines.

The event was also attended by various dignitaries and government officials, including Delaware Senator Christopher Coons.

“Prince Harry, thank you for your leadership, your heart, your vision, for keeping your mother's legacy alive, and for inspiring a whole new generation around the world to engage in this important work to combat the scourge of landmines.

Earlier Monday, the Duke of Sussex also honored his mother's memory and chatted with Tessie Ojo, CEO of the Diana Award, and two of the charity's Legacy Award recipients about how young people can make a difference in the world.

Prince Harry will continue his trip on Tuesday, attending the UN, the Clinton Global Initiative, and the Travalist.
