Hariri said the government formation came four months late, but on time to close a chapter "we don't want to go back to" and start anew under the headlines of national unity and cooperation.

"National unity means sacrifice and overcoming personal interests and those of the parties and the sects," said PM Hariri.

Lebanon's new prime minister praised Lebanon's struggle against matters not even bigger countries can endure, referring to the assassination of President Rafik Hariri followed by the Israeli offensive in 2006 and the chain of internal strife and conflict on Lebanese ground.

Hariri said that trust in the perseverance of the Lebanese people made Lebanon overcome strife and the Israeli war.

Hariri stressed that the new government faces challenges and priorities that include a legislative workshop, administrative improvement, fighting corruption, ending sectarianism and implementing the Taef Accord.

"New government stands unified in face of Israeli threats and offers a cooperative hand to the Arab brothers," added Hariri.

PM Hariri concluded his speech by promising "to work hard (with everyone) for Lebanon".

Earlier on Monday, Hariri visited Free Patriotic Movement leader Michel Aoun who provided him with the names of his candidates.
