The family of Guantanamo Bay detainee Omar Deghayes will today be told the result of their High Court bid to force the Government to intervene in his case.

His relatives have had an anxious two-week wait after lawyers for the 37-year-old law graduate from Saltdean last month argued that Foreign Secretary Jack Straw had a legal obligation to seek his release along with the release of two other British residents, Bisher Al-Rawi and Jamil al-Banna, imprisoned at the camp.

The Argus is campaigning for justice for Mr Deghayes, calling on the British Government to intervene and demand the US give him a fair trial or release him. But today the High Court will decide if Foreign Secretary Jack Straw should be ordered to seek the release of Mr Deghayes.

Lawyers acting for Mr Deghayes argued in a judicial review that the Government has both a legal and a moral responsibility to step in and help the detainees. The Government argued it has no responsibility to help Mr Deghayes as he was not a British citizen and in any event, to do so might be "counter-productive".

Lord Justice Latham is expected to give the court's decision today.

At the hearing of the case in March, the families' barrister Tim Otty argued the Government's refusal to intervene was legally unsustainable and said it was an abuse of power that violated the detainees' and their loved ones' fundamental human rights.

He claimed there was compelling evidence each of the three had been "severely tortured".
