They knew: The UK government just lost their Court of Appeal case, and the judges have ruled that they must publish this incriminating information relating to the torture of a UK resident, so here it is

At the heart of this case was the principle that if a country shares intelligence with another, that country must agree before its intelligence is released. This 'control principle' is essential to the intelligence relationship between Britain and the US. The Government fought the case to preserve this principle, and today's judgement upholds it. It agreed that the control principle is integral to intelligence sharing. The court has today ordered the publication of the seven paragraphs because in its view their substance had been put into the public domain by a decision of a US court in another case. Without that disclosure, it is clear that the Court of Appeal would have overturned the Divisional Court’s decision to publish the material.

Mr Miliband [had claimed] that releasing the material - which they said showed Mohamed had suffered 'cruel, inhuman and degrading' treatment - would damage relations with the U.S. Grovel, grovel, bow and scrape: kowtow, crawl and lick their boots. Fawn and flatter, curry favor from morning until late at night: We cater to their every need, and keenly heed their faintest call.....(The Appeal Court judges flatly rejected Mr Miliband's claim.)
