"In conducting this review, it became apparent that in three parliamentary answers since February 2007 ministers had overstated by approximately 1,000 the numbers of detainees held by UK forces in the period since January 2004 and nine further answers contained minor inaccuracies. I have written separately to Honourable Members setting the record straight and have placed copies also in the Library of the House and I want to apologise unreservedly for these inaccuracies.
"We have also reviewed our records of detentions in the period from March to December 2003 when large numbers of individuals were captured by UK forces during the initial high intensity combat phase of the operation. Many of them were held for very short periods of time or were transferred to the US facility at Umm Qasr and then also released. This facility was run by the UK from late March to mid April 2003 at which point it was then transferred to US control.
"Given the circumstances in which the database was compiled, we cannot be confident that the data we hold today is entirely complete. On a small number of occasions, answers or statements provided by my Department have included figures relating to the position in 2003, which indicated that we initially held up to 5,000 Iraqi prisoners during this period of time.
"However, a significant number of these were held on behalf of other coalition forces. We now believe that UK forces transferred around 3,000 individuals to the detention facility at Umm Qasr between March and December 2003. However, I would ask the House to treat this figure as a best estimate.
"In areas outside Multi-national Division South East, UK forces have undertaken operations to capture individuals who were subsequently detained by the United States. These individuals do not feature in the data I set out above today.
"I want, however, to reassure the House that the review has however concluded that UK forces have exercised appropriately their responsibilities towards all captured personnel handed to US custody whether in MND SE or elsewhere, and uncovered no evidence of mistreatment.
"During the final stages of the review of records of detentions, we found information about one case relating to a security operation that was conducted in February 2004, a period which hon. Members, I am sure, will recall saw an increased level of insurgent activity as the transfer to Iraqi sovereignty drew closer.
"During this operation, two individuals were captured by UK forces in and around Baghdad. They were transferred to US detention, in accordance with normal practice, and then moved subsequently to a US detention facility in Afghanistan. This information was brought to my attention on 1 December 2008 and I instructed officials to investigate this case thoroughly and quickly so I could bring a full account to Parliament.
"Following consultations with US authorities, we confirmed that they transferred these two individuals from Iraq to Afghanistan in 2004 and they remain in custody there today.
