From BBC :
A Libyan military commander is taking legal action against Jack Straw, to find out if the ex-foreign secretary signed papers allowing his rendition.
Abdel Hakim Belhadj claims CIA agents took him from Thailand to Gaddafi-led Libya, via UK-controlled Diego Garcia.
His lawyers have served papers on Mr Straw after the Sunday Times reported claims that he allowed this to happen.
UK ministers have denied any complicity in rendition or torture and Mr Straw did not comment further.
He said he could not do so because of the ongoing police investigation into the UK's alleged role in illegal rendition.
Earlier this month, the BBC revealed that the UK government had approved the rendition of Mr Belhadj and his wife - Fatima Bouchar - to Col Muammar Gaddafi's regime, though it was unclear at what level.
On 15 April, the Sunday Times published an article, which quoted sources as alleging Mr Straw had personally authorised Mr Belhadj's rendition to Libya.
On Tuesday, Mr Belhadj's lawyers - Leigh Day & Co - served papers on Mr Straw, referencing the article and seeking his response to allegations that he was complicit in torture and misfeasance in public office.
The civil action is against Mr Straw personally - Mr Belhadj's lawyers believe it is the first time legal action of this kind has been taken against a former foreign secretary.
Mr Belhadj and his wife allege Mr Straw was complicit in the "torture, inhuman and degrading treatment, batteries and assaults" which they say were perpetrated on them by Thai and US agents, as well as the Libyan authorities.
They are seeking damages from Mr Straw for the trauma involved.
