Kabul, Afghanistan (CNN) -- No candidate won enough votes to secure outright victory in the first round of the Afghan presidential poll, the election commission said Thursday.
The election will proceed to a runoff on June 14 between former Foreign Minister Abdullah Abdullah and former Finance Minister Ashraf Ghani, the two candidates who received the highest number of votes.
In the first-round, in which around 7 millions Afghans voted on April 5, Abdullah secured 45% of the vote, while Ghani got 31.6%. A candidate needs to receive more than 50% of the votes to win the first round and avoid a runoff.
Preliminary results had been announced in late April, but had to be finalized after investigations into fraud complaints.
The final results from the runoff will be announced on July 22, the election commission said.
It's the third election since the fall of the Taliban in 2001, and is set to be the first democratic transfer of power in the fragile, war-torn country.
Abdullah was a vocal critic of the Taliban during their years in power, and although he was once an ally of incumbent President Hamid Karzai, serving in his government as foreign minister, he has in later years become an opponent.
He challenged Karzai in the 2009 election but dropped out after the first round to protest what he said was large-scale voting fraud.
Ghani is a former academic and U.S. citizen who gave up his passport to run for the Afghan presidency in 2009. He worked as an adviser to Karzai and also as finance minister in his Cabinet.
