CAIRO  - Lebanese Prime Minister Fuad Siniora arrived in Cairo on Wednesday for talks on his country's presidential crisis after the failure of an Arab League rescue plan.

The Western-backed Siniora was due to meet President Hosni Mubarak on Thursday, officials said.

Lebanon has been without a president since Emile Lahoud stepped down on November 23 at the end of his term.

The head of the Cairo-based Arab League Amr Mussa held marathon talks with rival Lebanese political leaders last week, but failed to win their support for a plan to solve the crisis.

The Arab plan calls for the election of army chief General Michel Sleiman as president, the formation of a national unity government in which no one party has veto power, and the adoption of a new electoral law.

The Western-backed ruling majority has accepted it but the Hezbollah-led opposition, which is backed by Syria and Iran, is demanding that the opposition be given a third of the seats in a new government to ensure veto power.

Mussa left Lebanon on Sunday without making any breakthrough on the eve of a planned parliament session to elect a new president.

The session was then postponed until February 11 -- the 13th such delay since September.

Mubarak told reporters on Wednesday that the Arab plan "is the best initiative on the political scene." -AFP
