The body parts and tissue of soldiers killed in Afghanistan have been kept by the Ministry of Defence without the permission of their families.
Officials have admitted that six body parts and more than 50 tissue samples were retained by the Royal Military Police.
They were discovered last month when a new manager was appointed at the Military Police's Special Investigations Branch (SIB).
An urgent investigation has been launched and the MOD are trying to identify and inform the families affected.
The body parts were reportedly found at the John Radcliffe Hospital in Oxford, while the tissue samples - which were kept on laboratory slides for matching or identifying the dead soldiers - were discovered at the SIB's headquarters at Bulford Garrison in Wiltshire. It is believed that because multiple samples were taken for each case, the number of families affected is likely to be less than 60."
