Nairobi: Kenya's opposition candidate has called on President Mwai Kibaki to concede defeat in the presidential elections.

Raila Odinga has also accused Kibaki of fraud, adding: "This government has lost all legitimacy and cannot govern.''

Odinga clung is officially 38,000 votes ahead of the current president but the count was suspended on Saturday after trouble flared in the electoral commission office and allegations of vote fixing were made.

Alexander Graf Lambsdorff, chief European Union election monitor for Thursday's election, added to the concerns.

He said: "There is a big question mark over the tallying of results. Our observers have been turned away from several tallying centers without being given results."
