BRATISLAVA (AFP/Reuters) - Organisers of Afghanistans presidential run-off will be able to reduce but not eliminate the kind of election fraud, which marred the initial vote, the UN special envoy to Afghanistan said on Friday. I do not expect I will be able to eliminate fraud in two weeks time. I think that is beyond the realm of what is possible in such a short time, Norwegian diplomat Kai Eide said during a NATO meeting of defence ministers in Bratislava. But I what I do expect, and what we will try to do, is to reduce the level of fraud. With so little time to prepare for the run-off, Eide said he did not expect to completely prevent electoral fraud but added: what I expect and what we will try to do is to reduce the level of fraud. He said UN officials would monitor the government to ensure those linked to fraud would not work at polling places next month. Eide estimated about 50-60,000 polling workers would be needed. The election would be easier to organise in some ways compared to the last round, as there were only two candidates instead of 41 and no provincial polls, he said. The UN envoy said he was also concerned about turnout, as many Afghans viewed the election as finished and a public information campaign would be needed to educate voters about the second round. Many Afghans believe the elections are over, he said. Turnout in the first round on August 20 was about 38 percent. International election observers were urgently needed for the run-off, Eide said, calling on the European Union to move quickly to provide teams of monitors. Eide said the UN-backed investigations of electoral fraud showed that the countrys constitutional process and institutions worked the way they should. We did not manage to prevent fraud during the 20th August round, that is quite obvious, he said. But what is important we did manage to detect it. He dismissed criticism from his American ex-deputy and former senior diplomat, Peter Galbraith, who was sacked in September after protesting how Eide handled fraud allegations. Peter Galbraith to me now is a footnote in the electoral history of Afghanistan. He said a lot. I believe I have been proven to be right in my belief in institutions. We detected fraud as I had expected, Eide said. Asked about Galbraiths concerns that the next government would lack legitimacy, Eide said if authorities adhere to the countrys constitution, the election can produce a legitimately elected president with a majority of votes. After a clear winner is determined in the run-off, it was vital that the new government take clear steps to combat corruption and deliver services to win the trust of the Afghan people, as well as international donors, he said. The government suffered a confidence gap as many Afghans lacked faith in Kabul and international allies also harboured serious concerns, Eide said. Continued international support for Afghanistan would be endangered without signs of improvement in the Kabul governments performance, he said.
