Shadow Defence Secretary Nia Griffith has welcomed an inquiry into the deaths of two soldiers at a Ministry of Defence base in Pembrokeshire.
Royal Tank Regiment corporals Matthew Hatfield, 27, and Darren Neilson, 31 died when an ammunition round exploded as they were in a tank at Castlemartin Range on Wednesday.
Two other soldiers remain in a serious condition in hospital.
The MoD, Dyfed-Powys Police and Health and Safety Executive are investigating.
Ms Griffith said “they’re quite right to hold a proper inquiry”.
