A campaign group representing prisoners detained for terrorism has compiled reports from a large number of detainees and former detainees who claim that the security and intelligence services were aware of their torture and mistreatment and did nothing to stop it.
In some cases they claim that MI5 and MI6 officers were present during the mistreatment and in others that questions were fed to their interrogators or that officers questioned the suspects shortly afterwards.
The cases follow a decision last month by the Attorney General to launch a police investigation into the alleged collusion of MI5 in the treatment of Binyam Mohamed, the former Guantanamo Bay prisoner, and could lead to a large number of new court cases.
The Daily Telegraph reported last week that MI5 and MI6 had identified 15 cases where their officers had alerted senior personnel to possible mistreatment but no further action was taken.
The security and intelligence services acknowledge that they were swamped by cases in the aftermath of the invasion of Afghanistan and later tightened up their procedures but the latest allegations claim there was a systematic approach to the abuse that went beyond that period.
Asim Qureshi of Cage Prisoners, who produced the report, told the Daily Telegraph: "At first we thought these were cases of individual abuses but the more we saw and the more testimony we heard, the more we realised there was pattern.
"We were seeing interviews by MI5 and MI6 alongside the use of torture by other countries. This has been very, very systematic and that is what concerns us most. There has been a policy to keep prisoners beyond the reach of law and turn a blind eye to torture.
"We believe that the government is going to pass off the case of Binyam Mohamed as an isolated incident and use witness B [the officer allegedly involved] as a scapegoat but we believe it is important to put this in the context of what has been happening in the last seven or eight years."
Many of the allegations in the latest report, to be published next week, are already well-known but the group has talked to 10 individuals who are making new allegations that British security and intelligence officers colluded in their mistreatment of which six are completely new cases of alleged torture.
All of the alleged mistreatment took place abroad and the report lists a number of countries including Afghanistan, Pakistan, Egypt, Syria, Jordan, Morocco, the United Arab Emirates and Kenya.
A number of those making allegations were transferred and then released from Guantanamo Bay, while others are serving prison sentences in Britain for terrorism offences.
All the individuals are British citizens or British residents and the most recent case is that of Azhar Khan, a former terrorism suspect arrested in Egypt last year, whose brother-in-law led the fertilizer bomb plot against the Bluewater shopping centre and Ministry of Sound night club.
The list also includes seven former Guantanamo Bay prisoners who have launched a compensation case, including Moazzam Begg, a spokesman for Cage Prisoners, who was accused of receiving training from al-Qaeda.
The Foreign Office accepts that the treatment of prisoners in foreign countries often does not come up to British standards but say they must act where they are passed information that could prevent terrorist attacks.
They also point out that several allegations of British officers colluding in torture have been dismissed by courts in this country.
The Foreign Office deny the allegations and say they never condone torture.
