There is evidence that UK intelligence officers were aware of inappropriate interrogation techniques and mistreatment of some detainees held in other countries, a new report has found.
Revealing the findings of the detainee inquiry in the House of Commons, Cabinet minister Ken Clarke said the report identified 27 issues requiring further investigation.
The inquiry was set up by David Cameron in 2010 to investigate whether Britain was implicated in the improper treatment of detainees held by other countries in the aftermath of the 9/11 terrorist attacks.
There was also evidence that the Government or its agencies may have become "inappropriately involved" in some cases of rendition.
Mr Clarke said allegations of illegal rendition have harmed the reputation of the UK and its security services.
The inquiry examined more than 20,000 documents with the majority highly classified material.
