An exhibition featuring body armour worn by Diana, Princess of Wales on a visit to a minefield has opened at the National War Museum in Edinburgh.

Safer Steps: The Work of the Halo Trust highlights work carried out by the organisation, which is the world's largest humanitarian mine clearance group.

Ahead of the trust's 30th anniversary in 2018, the exhibition examines the development of the organisation and its current work through images, objects and interviews.

Visitors can see the body armour worn by Diana when she visited an Angolan minefield in 1997.

The armour is on loan from the Royal Armouries and will be displayed alongside famous images of Diana wearing it that were broadcast around the world.

The exhibits, alongside the personal stories of those whose lives have been rebuilt because of the trust's work, explore the devastating effect landmines have on communities.

Organisers also say the event illustrates how the campaign to ban landmines has become known around the world.

Maureen Barrie, exhibitions officer at National Museums Scotland, said: "This exhibition will offer a fascinating insight into the work of the Halo Trust.

"Over the past 30 years the trust has been working all over the world decommissioning mines, providing risk education and helping vulnerable communities get back on track.

"Safer Steps: The Work of the Halo Trust will highlight the importance of the organisation's ongoing work and how lives have been transformed as a result of this."

The trust was formed in 1988 and works across 19 countries and territories, saving lives and restoring communities threatened by landmines and other weapons.

In addition to the armour worn by Diana, the display will also include a range of decommissioned weapons, safety equipment and mine detectors.

James Cowan, chief executive of the Halo Trust, said: "We are honoured to be the subject of this exhibition. It is a tribute to the work of tens of thousands of local people over nearly 30 years who have made their own communities safer by clearing landmines and the debris of war.

"I hope it will provide the Scottish and international visitors to the museum with a picture of the dedication required to put countries back on their feet after conflict, and of the great impact Halo has had and continues to have on people's lives."
