David Cameron is to host his Libyan counterpart for talks in 10 Downing Street, it has been announced.
Abdurrahim El-Keib was appointed interim prime minister of Libya in October last year, days after the overthrow of dictator Muammar Gaddafi following a violent uprising backed by the UK.
Downing Street had no immediate information about the agenda for Thursday's meeting, but it is thought likely that Mr Cameron and Mr El-Keib will discuss the reconstruction of the country following last year's revolution, as well as the question of whether Gaddafi's son Saif al-Islam should be tried in an international court or in Libya.
Just days after the death of the only person convicted of the Lockerbie bombing, Abdelbaset al-Megrahi, they may also discuss whether any further evidence relating to the atrocity has emerged in the wake of the downfall of the Gaddafi regime.
Mr El-Keib spent much of his life working abroad as an academic and businessman in the United States and UAE, and played no part in Gaddafi's administration. He is understood to have helped fund the opposition from exile.
Elections for a national assembly for Libya are expected in June, though no date has yet been set.
