David Cameron's government is under increasing pressure to order a full inquiry into UK involvement in the "rendition" of terror suspects for torture by the CIA.

A senior Tory MP and a leading human rights lawyer have launched fresh calls following a damning US senate committee report into the response to September 11.

It came as the UK Government was forced to make another humiliating correction, announcing that Home Secretary Theresa May had not met the committee before it published its report, despite earlier confirming that she had.

Controversy has long hung over the UK's alleged involvement in rendition.

Earlier this week detectives investigating claims Scottish airports were used by CIA planes carrying terror suspects to secret prisons were instructed by the Lord Advocate Frank Mulholland to "consider" the 500-page Senate report.

A decade ago The Herald revealed that an aircraft linked with prisoner transfers - the so-called Guantanamo Bay Express - stopped in Prestwick.

Last night senior Tory backbencher Andrew Tyrie, the chairman of the all-party parliamentary group on extraordinary rendition, said the publication of the US Senate Intelligence Committee report on the CIA's torture programme should act as a model for a similar British inquiry.

His call was backed by Anthony Peto QC, who said: "The use of torture, or the knowing facilitation of torture by our Government, is contrary to core British values and undermines our freedom and democracy."

Their case appeared to be bolstered by former security minister Admiral Lord West, who suggested that UK security agents could have known about CIA torture plans.

Mr Tyrie, who is also chairman of the influential Treasury Select Committee, said the US report "highlights the UK's failure adequately to investigate allegations of its own facilitation of rendition - that is, kidnapping suspects and taking them to places where they may be maltreated or tortured".

He said: "Until the scope and limits of the UK's involvement are fully known, allegations - whether true or not - will continue to erode public confidence in our intelligence and security services. That is not in the public's interest any more than it is in the security services' interests."

Last night the Foreign Office blamed a "clerical error" for Mrs May's inclusion on a list of those who met with the committee.

Downing Street had confirmed the Home Secretary had met with the senators and that the encounter would have covered a "wide range of issues".

Mrs May will be questioned on the CIA's detention and interrogation programme by the Home Affairs Select Committee on Monday.

Lord West, who was also among those listed, said his meeting with the committee, in October 2009, focused on cyber security and he "absolutely didn't lobby any committee" about the report.

Downing Street has confirmed that UK spies spoke to their US counterparts to discuss potential redactions to the report on "national security grounds" - after initially suggesting that none had been requested.

A spokeswoman insisted however that: "My understanding is that no redactions were sought to remove any suggestion that there was UK involvement in any illegal torture or rendition.

"There was a conversation between the agencies and their US counterparts on the executive summary. Any redactions there would have been on national security grounds."

Lord West conceded that there may have been the "odd case" where British agents were aware of torture being carried out by the CIA at a time when it was not clear "exactly what their position was in regards to these things".

Deputy Prime Minister Nick Clegg has said a full judicial inquiry may still be required into allegations of British complicity if police and parliamentary probes fail to answer key questions.

Tom Davies, Amnesty UK's Stop Torture Campaign manager, said: "At the moment the UK is acting like it's afraid to turn over the rock for fear of what it will find underneath."

Meanwhile the United Nations' special rapporteur on human rights and counter-terrorism said senior US officials found to have sanctioned the use of torture by the CIA should face the "gravest penalties".

Ben Emmerson QC said individuals who authorised the use of waterboarding and other so-called "enhanced interrogation" techniques were "as criminally responsible as those who actually perpetrated it".

The international lawyer said officials and politicians involved in the programme could face arrest in any country because torture is a crime of universal jurisdiction.
