"The chance for a breakthrough in the Lebanese crisis at the summit have become weak, with Saudi low-ranking presence and Lebanese absence." Arab diplomatic sources were quoted by local As-Safir Daily as saying.

The case of Lebanon will be dealt with in Damascus summit the same way it was handled during the AL foreign minister meeting in Cairo on January 6, the source added.

AL initiative set at Cairo meeting a three-point plan to solve the Lebanese problem. The plan calls for the immediate election of Army commander Michel Suleiman as president, forming a national unity government, and the adoption of a new election Law.

Moussa failed to implement the Arab plan following a number of trips and a series of meeting in Lebanon.

Until now, no agreement was reached between the ruling coalition and the opposition to elect a new president for Lebanon.

The opposition insisted on its demand of veto power in the new government, while the ruling coalition refused to discuss the shape of the government before electing a president.

Lebanon crisis reflects Arab differences

Lebanese Parliament Speaker Nabih Berri, who is in opposition bloc, postponed Tuesday a parliamentary session for presidential election scheduled for March 25 until April 22.

It is the 17th postponement since September 25 last year, which means there will be no Lebanese president to attend the Damascus summit.

Egyptian foreign minister Ahmad Abu Gheit warned on Monday that the turnout at the summit would be poor if the election session in Lebanon was postponed again.

Egypt and Saudi Arabia have linked the level of their participation in Damascus summit to a solution to the presidential crisis in Lebanon.

Saudi Arabia will be represented by its ambassador to the AL at the Damascus summit, while Egypt is sending its Minister of Legal and Parliamentary Affairs.
