President Robert Mugabe could lose Zimbabwe's presidential election next month in spite of his efforts to rig the result, senior US government officials say. Unofficial polls conducted by Zimbabwean organisations and seen by US officials show there would be a good chance Mr Mugabe would get only 25-30 per cent of the vote if the election was fair. The officials said this was despite widespread intimidation of the opposition and political violence over the past 18 months. However, they fear Mr Mugabe has the ability to "win" an additional 20 per cent by further manipulation of the vote and thus extend his 22-year rule.
