Kenya's main opposition party has declared victory in the country's presidential election, despite continued delays in announcing official returns.

Musalia Mudavadi of the Orange Democratic Movement says Raila Odinga is Kenya's president-elect based on the party's own vote tally. Mudavadi is Mr. Odinga's vice-presidential running mate.

Partial official results released Saturday show Mr. Odinga with 3.7 million votes, compared to 3.4 million for incumbent President Mwai Kibaki.
