The four recruits' families want a public inquiry into the deaths

The recruits aged 17 to 20 died at Deepcut Barracks between 1995 and 2002. Their deaths were recorded as suicide.

An MoD spokesman said a national review of defence training establishments was currently ongoing which could see some bases closed.

But he said no final decision on the Surrey base or any others would be made until at least next year.

'Best value for money'

Deepcut has been the subject of a major police investigation following the deaths of the young soldiers.

The four soldiers to die at the Royal Logistics Corps HQ were Geoff Gray, 17, from Durham, Sean Benton, 20, from Hastings, East Sussex, James Collinson, 17, from Perth, and Cheryl James, 18, from Llangollen, north Wales.

On 4 March Surrey Police released its fifth and final detailed report into the deaths, highlighting shortcomings in the Army's approach to training.

The same day it was announced MPs are to hold an inquiry into the events surrounding the deaths at the barracks.

The investigaions have been prompted by families of the dead soldiers who are unhappy with explanations of the deaths after initial investigations by the Army concluded they had committed suicide.

We don't want it shutting down and staff being scattered right across the globe and paperwork being 'lost' Geoff Gray, father of Pte Gray

Now the MoD has confirmed the base is being studied in a national review, along with 27 other armed forces training facilities.

The MoD said it was focusing on all main training sites across the country "to ensure that we get the best value for money".

A spokesman said there was no question of Deepcut closing at the moment.

"It's a decision which is a long way from being taken.

"At most, it's a possibility," he said.

The government is still considering the families' request for a public inquiry.

But Pte Gray's father, Geoff, said it would have to happen before Deepcut closed.

"We don't want it shutting down and staff being scattered right across the globe and paperwork being 'lost.'"

Yvonne Collinson, mother of Pte James Collinson, said: "We don't want vital witnesses disappearing into the woodwork."
