Al Jazeera has obtained the mobile phone wiretaps of Al-Baghdadi al-Mahmoudi, Muammar Gaddafi's prime minister and a loyal ally to the Libyan leader almost to the end.

In September, al-Mahmoudi publicly recognised the new rulers of Libya but was arrested in Tunisia soon afterwards on charges of entering the country illegally. Charges against him were subsequently dropped but he remains in prison in Tunis, which has refused to extradite him to Libya.

Al-Baghdadi is the most senior member of Gaddafi's regime in custody and, in the absence of others, he will be expected to answer many questions that remain about the final days of the former regime.
