Abdullah leading Afghanistan poll
The chairman of the Independent Election Commission, Ahmad Yousuf Nouristani, said today that Mr Abdullah had 44.9% of the vote and ex-finance minister Ashraf Ghani Ahmadzai came in second with 31.5%.
The preliminary results are due to be finalised on May 14 after investigations into fraud complaints.
Electoral law requires a run-off between the top two candidates if no one candidate gets a majority. A run-off should be held within 15 days of final results.
