Top Lebanese officials agreed yesterday on the make-up of a new government that had been threatened by last-minute squabbling over the electoral law and key Cabinet portfolios, a senior political source said. The line-up would include 30 mainly ministers, the source said, charged with leading the country to elections due in May but likely to be delayed while a new electoral law is drafted and passed by parliament. The deal over the new government, expected to be announced shortly, was struck at a meeting between President Emile Lahoud, Prime Minister Omar Karami and Parliament Speaker Nabih Berri after a day of intensive talks.Lebanon has been without a government since anti-Syrian protests forced Karami and his government to resign on February 28. Karami later agreed to form a new Cabinet to prepare for the election but had so far been unable to form a government, much to the ire of Lebanon's opposition which expects to win a majority in a house now dominated by Syria's allies. The new Cabinet's main task will be to draft the electoral law and supervise the polls to be held after Syria completes the pullout of its troops from Lebanon by the end of April. The opposition as well as the United States, France and the United Nations have called on the authorities to hold the elections on schedule.
