Jonathan Evans: Unprecedented rebuttal
The head of MI5 has denied officers withheld information over what it knew about the the torture of a UK resident.
In an unprecedented move, Jonathan Evans defended the security service against claims it misled MPs over the US's treatment of Binyam Mohamed.
The Court of Appeal earlier ruled that Mr Mohamed could learn what MI5 knew about his 2002 mistreatment while in secret detention in Pakistan.
The home secretary has attacked the media's "baseless" accusations.
Mr Evans's highly unusual decision to respond came amid a row over changes made to the Court of Appeal's judgement in the Binyam Mohamed case.
Following the judgement, it emerged that the leading lawyer for the government, Jonathan Sumption QC, had lobbied the judges to remove a paragraph from the draft judgement.
The barrister said the paragraph was "exceptionally damaging" because it left the impression that MI5 did not have a culture of respecting human rights and did not object to "coercive interrogation techniques".
Mr Sumption told the judges he believed the words, written by Master of the Rolls Lord Neuberger, could be read to mean that MI5 had also misled the Intelligence and Security Committee.
The disputed paragraph does not appear in the final judgement - but Channel 4 News claimed on Thursday that it related to US documents concerning Mr Mohamed's treatment, which MI5 allegedly failed to disclose to the committee.
In an article
published in the Daily Telegraph on Friday,
Mr Evans said that his officers had never misled parliamentarians and operated within the law.
He said claims of a "culture of suppression" at the heart of the security service were "the precise opposite of the truth".

"People who choose to work in the service do so because they want to protect the UK and its liberties," wrote Mr Evans.
"We are an accountable public organisation and take our legal and oversight responsibilities seriously.
"The material our critics are drawing on to attack us is taken from our own records, not prised from us by some external process but willingly provided by us to the court, in the normal way. No cover-up there."
Adding his voice to the row, Home Secretary Alan Johnson said claims in some parts of the media that MI5 had orchestrated a cover-up were a "ludicrous lie".
"The security services in our country do not practice torture," he said.
"They do not endorse torture, they do not encourage others to torture on our behalf, they do not collude in torture, full stop.
"It's a free society, and that's actually what the security services are out there to protect. But occasionally they have to actually argue back. They can't allow that kind of misrepresentation to carry on un-thwarted."
But Clare Algar, executive director of Reprieve, which represents Binyam Mohamed, said: "It's incredibly offensive to suggest that the people who are bringing to light the ways in which the British intelligence service and US intelligence service have behaved badly could be responsible for giving succour to the enemy.
"The thing that gives succour to the enemy is the bad behaviour in the first place - and that's the reason we shouldn't be involved in torturing people."
