Prince Harry has expressed his frustration that countries which supplied landmines to African countries are doing nothing to get rid of them, following a visit to clearance projects in Angola.
The 28-year-old followed in his mother's footsteps by taking up the cause of the Halo Trust.
Guy Willoughby, Halo's chief executive, said the prince was left "irritated" and with a "bee in his bonnet" that nations are not putting in any funds to clear landmines they supplied 25 years ago.
He said the charity was "delighted" at Harry's involvement after seeing the impact of Diana's famous visit in 1997.
"The minefields that his mother visited are all now shops and roads and there's even an estate agent's on one of them," Mr Willoughby said.
