Opposition leader Morgan Tsvangirai beat Mugabe and two other candidates in the first round of voting March 29, but did not win the 50 percent plus one vote necessary to avoid a runoff, scheduled for June 27. Tsvangirai's party, foreign diplomats in Zimbabwe, and Zimbabwean and international human rights groups accuse Mugabe of unleashing violence against the opposition to ensure Mugabe wins the runoff. Zimbabwean government and party spokesmen have repeatedly denied such allegations.
