KABUL (Reuters) - The front-runner in Afghanistan's bitterly disputed presidential election on Wednesday called for the release of results of a fraud investigation and said that any political deal to end the crisis should not result in a "two-headed government."

Two months of tension over the election have already marred the smooth transition that the U.S.-led military force had hoped would mark its exit, 13 years after the war to oust the Taliban's radical Islamist regime.
