An Afghan official says the release of preliminary results from a runoff vote in the presidential election might be delayed, a move that would further complicate a process that has been marred by fraud allegations.

The spokesman for the Independent Election Commission, Noor Mohammad Noor, said Tuesday that the panel is considering a possible postponement of the announcement because it still needs to audit results from 1,930 polling stations in 30 provinces.

According to the official timetable, initial results are due Wednesday and final results are due on July 22, with the inauguration date for the new president scheduled for Aug. 2.

Abdullah Abdullah, one of the two candidates vying to replace President Hamid Karzai, has alleged that supporters of his rival Ashraf Ghani Ahmadzai engineered massive fraud.
