I am delighted that Shaker Aamer is finally to be released from Guantanamo. This is something I have worked, campaigned and spoken for, along with groups including Cage, which I am proud to support and which the government is attempting to ban.

We cannot give back to Shaker the thirteen years of imprisonment without charge, let alone trial. We cannot undo the physical and mental damage of all the torture. We can see him reunited with his family and demonstrate our support and affection.

Just as nobody has been charged over the illegal waging of a war of aggression against Iraq, nobody faces prosecution over the equally illegal policy of complicity in torture, to which policy I personally was an eye-witness.

The reason Shaker has been detained longer than any other British resident is that he was tortured with MI6 personnel directly in the room, as opposed to waiting outside. If the British establishment were not totally corrupt, his return to the UK would finally make it impossible to avoid prosecutions over torture, up to and including Dearlove, Straw and Blair.

The one thing we know for certain about the stinking cesspit of the British political system, is that justice is not possible.
