November 24th Dunidda \ Africa Libya's government says Mr Sanussi, a brother-in-law of Col Gaddafi, was arrested at his sister's home in the southern town of Sabha on Sunday. Saif al-Islam had been on the run since NTC forces took Tripoli in August, six months into the uprising.
Mr Keib has promised that Saif al-Islam will receive a fair trial after concerns were raised about the possibility of ill-treatment given the killing of Col Gaddafi after his capture in Sirte.
'Competence' On Monday, Mr Keib said he was finalising his cabinet with the NTC and expected to announce the line-up on Tuesday.
Prime Minister-designate Abdurrahim al-Keib has spent much of his career in the US as an academic
"We will use competence as a basic measure and this way we will be able to include all of Libya's regions," he told a news conference.
An NTC source quoted by Reuters news agency said the local military commander in the western town of Zintan, Osama al-Juwali, had been designated defence minister.
Libya's deputy UN ambassador Ibrahim Dabbashi had been named foreign minister, interim oil minister Ali Tarhouni was moved to finance and oil industry executive Hassan Ziglam was taking over the oil ministry, Reuters said, but those names have not been confirmed.
The BBC's Rana Jawad, in Tripoli, says the first test of the new government will be to successfully centralise Libya's political and military powers.
Only then will the government be able to proceed with drafting a constitution and eventually hold Libya's first democratic elections in its modern history, our correspondent says.
Col Gaddafi was overthrown and his supporters defeated after a nine-month insurgency that began in the eastern town of Benghazi and eventually swept across the rest of the country.
Militias in different areas, joined by defectors from the army, were aided by Nato forces who bombed Col Gaddafi's forces under a UN mandate to protect civilians.
