BEIRUT (Reuters) – Lebanese President Michel Aoun did not intend to revoke prime minister designate Saad al-Hariri’s mandate when he wrote to parliament last week declaring that Hariri could not form a government, Aoun’s son-in-law says. Hariri was nominated in October to form a cabinet after Hassan Diab’s government resigned following a Beirut port explosion which killed 200 people and damaged large swathes of the capital. But Hariri and Aoun have been at loggerheads for months over cabinet positions, blocking the formation of a government. Diab and his cabinet have stayed on in a caretaker capacity.
