Prime Minister Abiy Ahmed's Prosperity Party secured a new five-year term in the first round in June by claiming 410 out of 436 contested seats in the federal parliament.
More than seven million voters can choose representatives for 47 federal parliamentary seats and 105 regional ones, electoral board spokeswoman Solyana Shimeles said Monday.
Ethiopia has 547 constituencies nationally, but the electoral board has written off plans to hold elections in Tigray, which is currently mostly under TPLF control.
