Former Afghan foreign minister Abdullah Abdullah, who quit the presidential poll race recently, says Hamid Karzai’s re-election has “no legal basis”. Mr Abdullah, Mr Karzai’s main rival, said the current government cannot bring legitimacy to the troubled nation and will fail to control corruption.
He also criticised the election commission for declaring Mr Karzai the winner of the 20 August poll.
On Sunday, Mr Abdullah announced that he was withdrawing from the election.
The commission proclaimed Mr Karzai the victor on Monday, cancelling a planned runoff and ending a political crisis two and a half months after a fraud-marred first round.
Hundreds of thousands of votes were discounted from August’s first round of voting.
An investigation by the UN-backed Electoral Complaints Commission (ECC) said Mr Karzai’s share of the vote was 49.67% - below the crucial 50% plus one vote threshold needed to avoid a second round.
