Shaker Aamer: Britain under pressure to track activities of released Guantanamo prisoner

Britain is under renewed pressure from the United States to track the activities of the final British resident to be released from Guantanamo Bay, as costs to the UK taxpayer spiral to at least £20 million.

The Telegraph understands high-level discussions have taken place between London and Washington over how the British security services will monitor potential threats posed by Shaker Aamer, who flew back to Britain on Friday.
