Over 36.8 million Ethiopians registered for Sunday's polls, but analysts say the election in Africa's second-most populous nation falls far short of true democracy. The opposition also alleges the government has used authoritarian tactics to guarantee victory.
The outgoing Ethiopian parliament had one opposition MP, and one of the main opposition candidates, Yilekal Getinet, accused the government of "closing" political space.
Voters stood peacefully in lines in the capital Addis Ababa. Stations were calm, without long queues but a regular flow of people passing through to cast their ballots.
"I except the EPRDF to win - but maybe the opposition will get more seats so there will be more discussion about what the government is doing," said Wossen, who was waiting to vote. "It is better for the country -- now there is only one opposition MP and no discussion."
