Four Algerian terror suspects being detained in Britain have agreed to be deported.
The men have voluntarily agreed to return home after being held without trial in Britain for a number of years.
A Home Office spokeswoman said: "We do not comment on operational matters.
"It remains our view that those detained on strict bail remain a real risk to national security in this country."
In June last year two Algerian men suspected of being international terrorists were voluntarily removed from Britain after dropping appeals against Government deportation moves.
The pair - who could only be identified as "Mr I" and "Mr V" - were both former "Belmarsh detainees".
Mr V was acquitted in April 2005 of involvement in a plot to poison Londoners with the toxin ricin. It is understood he was the first of seven Algerian terror suspects to leave British soil after beginning voluntary moves to return in protest at "inhumane" treatment in the UK.
Mr I, who was alleged to be a senior member of the Abu Doha group, was imprisoned without charge or trial for three years under the Government's controversial Internment Powers.
The Home Office has struggled for years over what to do with terror suspects. Internment laws brought in after the September 11 terror attacks in the United States were knocked down by the Law Lords and the replacement control order regime has also been criticised.
Ministers were unable to forcibly deport people like Mr I and Mr V to Algeria because human rights laws say they cannot be returned to a country where they may face torture or ill-treatment.
