'Torture complicity': Key cases
As the government announces a judge-led inquiry into allegations British security services were complicit in torture, a look at the string of cases the Joint Committee on Human Rights said link the British intelligence and security agencies with claims of mistreatment.
BINYAM MOHAMED: RENDITION TO MOROCCO
The most well-known case involves Binyam Mohamed, a British resident who, until earlier this year, was being held in Guantanamo Bay. He is now back in the UK and is fighting a legal battle to have secret papers in his case made public.
Mr Mohamed was detained in Pakistan in 2002 and handed over to US authorities. He was moved to Morocco and Afghanistan before being finally detained at Guantanamo Bay. Mr Mohamed says that he was abused in Pakistan and tortured in Morocco.
The High Court has heard that an MI5 officer interviewed him in Pakistan. In July, it emerged that the same officer visited Morocco three times during the period that Mr Mohamed was being detained and allegedly mistreated there.
Mr Mohamed has accused the British security services of being complicit in his alleged mistreatment in two ways.
Firstly, he says that his Moroccan interrogators were asking him questions about his life which could only have come from British authorities. Secondly, he says that the British government failed to do enough to find out what was happening to him after he was "rendered" to Morocco.
Mr Mohamed has not been charged with any offence since being allowed to return to the UK. The Metropolitan Police has launched an investigation of the MI5 officer who interviewed him in Pakistan.
SALAHUDDIN AMIN: JAILED FOR LIFE
Salahuddin Amin was jailed for life in 2007 for his part in plotting a major bomb attack in the UK.
The Luton man's conviction, along with four other Britons, marked a major turning point for counter-terrorism detectives who had penetrated an al-Qaeda inspired network that stretched across three continents.
Amin was living in Pakistan at the time of the conspiracy and his trial heard that he had played the role of a facilitator, linking British plotters with extremists with the technical expertise needed for a bomb plot.
However, throughout his trial and since being sent to jail, Amin has maintained that he was tortured following his arrest in Pakistan.
Amin was held in the country for 10 months and MI5 officers conducted a string of interviews with him during this detention before he was returned to the UK to face trial.
He says officers from Pakistan's Inter-Services Intelligence (ISI) beat him and threatened him with an electric drill. In pre-trial hearings back in London, a judge ruled that his mistreatment did not amount to torture.
Amin has now begun a wide-ranging legal action against the British authorities, saying they were complicit in his abuse.
RANGZIEB AHMED: MENTIONED IN PARLIAMENT
In December 2008, Rangzieb Ahmed, formerly of Rochdale, was the first British man to be jailed for directing terrorism outside of Northern Ireland.
He is alleged to have played an important role in Pakistan linking British activists with Jihadist leaders.
Human rights campaigners in Pakistan highlighted his case before he was deported to the UK to face trial.
He says that he had his fingernails pulled by a Pakistani torturer and was held in inhumane conditions for 13 months.
The judge at his Manchester trial refused to throw out the case and rejected Ahmed's claim that his fingernails were pulled before he had been interviewed by MI5.
However, in July this year, the former Conservative frontbencher David Davis used the legal protection of Parliamentary privilege to make allegations about Ahmed's treatment, relating to information raised in secret before the trial.
He told MPs that he had information that Greater Manchester Police had sufficient grounds to arrest Ahmed, but he was allowed to leave the UK in 2006.
British intelligence officers then suggested to their Pakistani counterparts that they arrest Ahmed, Mr Davis alleged.
Mr Davis claimed MI5 subsequently supplied the Pakistani interrogators with questions. And when Ahmed later told visiting MI5 and MI6 officers he had been tortured, they did not return.
"A more obvious case of outsourcing of torture, a more obvious case of passive rendition, I cannot imagine," Mr Davis told MPs.
