U.N. says “not possible” to finish Afghan vote audit by Sept. 2

KABUL, Aug 28 (Reuters) - Afghanistan's U.N. representative told President Hamid Karzai on Thursday it was “not possible” to finish an audit of a disputed election by Sept. 2, when Karzai had hoped to see a new leader inaugurated, Karzai's office said.

The United Nations is supervising the audit of votes from a run-off ballot between the two candidates, Abdullah Abdullah and Ashraf Ghani. They have both claimed victory in the election intended to mark the country's first democratic transfer of power.

“The envoy said he is hopeful that the audit process will end by Sept. 10,” Karzai's office said in a statement.
