Robert Mugabe, the nation's first prime minister, has been the country's only ruler (as president since 1987). In April 2005, the capital city of Harare embarked on Operation Restore Order, ostensibly an urban rationalization program, which resulted in the destruction of the homes or businesses of 700,000 mostly poor supporters of the opposition. President Mugabe in June 2007 instituted price controls on all basic commodities causing panic buying and leaving store shelves empty for months. MDC opposition leader Morgan Tsvangirai won the most votes in the presidential polls, but not enough to win outright. In the lead up to a run-off election in late June 2008, considerable violence enacted against opposition party members led to the withdrawal of Tsvangirai from the ballot. Difficult negotiations over a power-sharing government, in which Mugabe remained president and Tsvangirai became prime minister, were finally settled in February 2009. Mugabe was reelected president in June 2013 in balloting that was severely flawed and internationally condemned.
