The United States special envoy to Afghanistan, Richard Holbrooke has said it is reasonable to hope for fewer irregularities in the Afghan presidential run-off poll than in the August election. Richard Holbrooke told reporters that one reason was that this time there were only two candidates, President Hamid Karzai and Abdullah Abdullah. The run-off has been called after no overall winner emerged from the first poll. <br/>Mr. Abdullah's spokesman said the officials from the government-appointed Independent Election Commission (IEC) should be replaced by people who both Mr Abdullah and President Karzai found acceptable. Mr Abdullah, a former Foreign Minister, has previously accused the commission of not being impartial. <br/> <br/><br/>
