The United Nations has begun investigating reports of widespread voting irregularities in Afghanistan’s presidential election on Saturday. All ballot counting has been stopped until the UN panel completes its investigation. On Saturday all 15 presidential candidates running against the U.S.-appointed incumbent Hamid Karzai announced they were boycotting the election citing voting security problems. Most of the candidates have called for a new election. Since then US and British diplomats have pressured the opposition candidates to accept the voting results. At least one leading opponent of Karzai has agreed to accept the findings of the UN investigation. Karzai, who is expected to win the election, dismissed the concerns of his opponents. He told reporters, “Who is more important, these 15 candidates, or the millions of people who turned out today to vote?”
