Earl Spencer, brother of the late Diana, Princess of Wales, spent three days in

Phnom Penh this week on a private visit to the Cambodia Trust, which provides services

to landmine victims.

"Landmines were one of [Diana's] main concerns at the end of her life,"

he said, adding that the two had discussed filming a documentary here.

"She was very keen on Cambodia over anything else."

He toured the British NGO's prosthetics school, met with technicians and amputees,

and gave the commencement speech at the March 26 graduation of prosthetic limb fitters.
