He received a two-year Terrorism Prevention Investigation Measure to restrict his movements in 2012.
But the order expires today and anti-terror cops and spooks will now have to track him round the clock at an annual cost to taxpayers of up to £3million — £8,000 a DAY. Security services believe the man visited training camps in Pakistan before the 2006 plot — which would have killed some 1,500 — was foiled.
But despite the alleged national security threat, the man is among seven terror suspects given lifelong anonymity after all their TPIMs — which typically restrict movements and the use of phones and laptops — expire at the end of the month.
The man can be known only as AY over fears identifying him could breach his human right to privacy or encourage vigilantism.
Where he is living or where he has lived in the past while being monitored must also be withheld.
Last night Tory MP Peter Bone said: “Human rights laws brought in with best intentions are being used to protect terrorists, not the public.”
A Home Office spokeswoman said: “If an individual engages in further terrorism-related activity, it will be possible to impose a new TPIM notice for a further two years.”
