Lords challenge on control orders

Ten terror suspects placed under controversial control orders - including at least two who are on the run - will argue the measures violate their right to liberty and a fair trial. The different cases will be considered at the same time by a panel of five law lords.

It will include Home Secretary Jacqui Smith's appeal against a ruling last year by the Court of Appeal, which said control orders imposed on six Iraqis were incompatible with Article 5 of the European Convention on Human Rights which prevents indefinite detention without trial.

One of the Iraqis, Bestun Salim, vanished before police could issue him with a replacement order and is still at large.

Another, who has not been named, disappeared on June 16 after 18 months on an order.

Salim is accused of links to the late insurgent leader Abu Musab al-Zarqawi, and was the first "controllee" to abscond.

He vanished from his Manchester flat last summer after being charged with seven offences of breaching his control order.

It is believed that Salim, formerly known only as LL, may have travelled overseas. He argued in court that he was Iranian.

A ban on naming him was lifted by the High Court in May.
