Jakaya Kikwete, presidential candidate for the ruling Revolutionary Party, has won Tanzania's third elections since multiparty politics were reintroduced in 1992, securing 87.4 percent of the vote, an official document showed Sunday. Kikwete was declared winner according to a National Electoral Commission document, of which The Associated Press obtained a copy. He had been widely expected to be elected Tanzania's fourth president since its 1961 independence from Britain. National Electoral Commission officials are shortly expected to announce the final results of Tanzania's elections, held on Wednesday.
