Afghanistan's election commission has announced preliminary results from last month's presidential runoff showing former finance minister Ashraf Ghani has the lead.
The commission said on Monday that Ghani garnered 56.4 percent of the votes in the preliminary tally, and former foreign minister Abdullah Abdullah received 43.5 percent.
Abdullah got the largest number of votes in the first round of the election in April.
He claims commission officials were involved in widespread fraud in the runoff. He has said he will not accept any outcome unless a full investigation is conducted.
The commission has admitted that senior security force officers and high-ranking government officials engaged in vote-rigging.
The commission plans to announce the final results after a committee investigates the fraud allegations.
Analysts say the dispute could deepen ethnic conflict, as Ghani and Abdullah have different ethnic support bases.
