(Writes through with denial)
By Jessica Donati and Hamid Shalizi
KABUL, Dec 2 (Reuters) - President Hamid Karzai denied on Monday that he had suggested delaying the elections scheduled for April next year to avoid the heavy snow that could cut off access to some parts of the country, as asserted by the poll's organisers.
The Independent Election Commission (IEC) chairman had told Parliament that Karzai suggested pushing back the elections to address concerns about snow blocking voters. Karzai's spokesman however denied that changing the date had been discussed.
"The president will never interfere in the affairs of the election commission nor he would allow others to do so," Aimal Faizi said.
The prospect of a delay was likely to worry the United States and critics of Karzai who fear he may be trying to drag out his second and final term.
Karzai is barred by the constitution from running for a third term and has so far refrained from backing any of the candidates, although he is widely expected to support his elder brother Qayum, seen as one of the front runners.
The president has also refused to sign a pact that would keep thousands of U.S. troops in Afghanistan after next year when most international troops pull out. His assertion the deal should wait until after the elections has been taken by some as evidence of his reluctance to step out of the limelight.
"Regarding the weather, there have been concerns," IEC chairman Yousof Nooristani told parliament's upper house on Sunday. "Even the president has suggested we could make changes to this (the election date) because he received complaints from the people."
"I told him we couldn't because the date is set, based on the constitution and electoral law."
But while electoral law states the date cannot be changed, one member of the IEC - appointed by Karzai's administration to organise the vote - said it could be delayed if the weather threatened to exclude groups of voters.
"That is possible, but one thing is clear. We are trying not to say this...it is premature," the commissioner told Reuters, asking to remain anonymous because he is not authorised to give statements to the press.
Critics at home and diplomats however have long feared that Karzai could use bad weather or poor security as a tool for pushing back the vote set to mark the first democratic transfer of power since the Taliban fell in 2001.
But the IEC's spokesman said that neither the organisers nor the president had authority to change the date.
"Some members of the upper house asked the chairman if the time could change because of the climate issue in the north of the country," IEC spokesman Noor Mohammad Noor said.
"No one can have the authority to change the date and time, because it is quite clear in the constitution."
The IEC chairman's assertion that Karzai advocated delaying the vote will come as a disappointment to Washington, engaged in the standoff over the signing of the security agreement.
Organisers already say poor security, a shortage of monitors and funding holes are undermining their ability to safeguard the process from the widespread fraud that marred the last poll in 2009.
Another deeply flawed election would undermine the attempts of Washington and its allies to foster democracy before the withdrawal of foreign troops.
Western nations, who have spent hundreds of billions of dollars on a conflict that has failed to end the Taliban insurgency, have pledged about a third less cash to the United Nations fund that will cover most of the election's costs compared with 2009, official U.N. figures show.
Corruption among election staff is rife, according to both U.N. and Afghan sources, and even those that want to remain independent fear their lives may be in danger if they try to stop fraud. Many important roles in the IEC remain vacant just five months before the poll.
There is also a severe shortage of female staff, which threatens to exclude most women from voting and makes polling stations for women harder to monitor.
If the pact with the United States is not signed, Western aid running to billions of dollars will be in jeopardy and confidence in the fragile economy could collapse amid fears the country will slip back into ethnic fighting or civil war.
The logic for setting the election date in early April was to minimise the risk of attacks by the Taliban insurgency. Because of heavy snow, fighting in Afghanistan tends to subside during the winter months. (Writing by Jessica Donati; Editing by Angus MacSwan)
