Afghanistan presidential election delayed to Sept 28

War-torn Afghanistan has delayed its presidential election until September 28, officials announced Wednesday, the second time the ballot has been put back and five months later than it was originally scheduled to be held.

The announcement by the Independent Election Commission (IEC) comes after speculation that the vote would be postponed to create space for US-led efforts to end the 17-year war with the Taliban.

The presidential ballot was originally scheduled for April 20, then delayed to July 20. Many observers had considered both dates unrealistic given the Independent Election Commission (IEC) is still finalising results of October's shambolic parliamentary elections.

The IEC said in a statement Wednesday that the vote had faced "numerous problems and challenges ... therefore holding the elections based on the timelines previously announced is not possible".

"In order to better implement the rule of election law, ensure transparency as well as voter registration, the presidential election, provincial council election as well as the parliamentary election of Ghazni province will be held on September 28," the statement said.

The election should go ahead, it added, "provided all relevant sides, especially the government and the international community, provide the IEC with the required budget on time".

A spokesman for President Ashraf Ghani, who plans to seek re-election, said the government respects the decision and is "fully prepared to cooperate with the IEC".

The statement did not mention the ongoing talks between the US and the Taliban, which have caused unease in Kabul as Washington seeks a way out of its longest war.

Afghan officials have voiced frustration at being sidelined in the process, complaining it undermines the legitimacy of the government in Kabul, which the Taliban dismisses as a puppet regime.

Earlier this month a close Ghani aide sparked a diplomatic spat with Washington by criticising the talks.

"We don't know what's going on. We don't have the kind of transparency that we should have," Hamdullah Mohib, Afghanistan's national security advisor, told media during a visit to Washington.

"The last people to find out are us."
