Election officials in Ethopia say provisional results show the ruling party has won a majority of parliamentary seats.
The National Electoral Board gave the ruling Ethiopian People's Revolutionary Democratic Front 274 out the 547-seat parliament.
Parties allied with Prime Minister Meles Zenawi won another 15 seats, and opposition groups - who have claimed fraud - were given 174.
The results are based on a final vote count of 463 seats.
Final results will be announced after a re-balloting in several areas and investigations into allegations of fraud and other complaints.
Both the ruling party and opposition groups have already claimed victory in the May 15 poll.
