Government and politics

Zimbabwe is a semi-presidential system republic, which has a parliamentary government. Under constitutional changes in 2005, an upper chamber, the Senate, was reinstated. The House of Assembly is the lower chamber of Parliament. President Robert Mugabe's Zimbabwe African National Union – Patriotic Front (commonly abbreviated ZANU-PF) has been the dominant political party in Zimbabwe since independence. In 1987 then-prime minister Mugabe revised the constitution and made himself president. His ZANU party has won every election since independence. In particular, the elections of 1990 were nationally and internationally condemned as being rigged, with the second-placed party, Edgar Tekere's Zimbabwe Unity Movement, winning only 16% of the vote. Presidential elections were again held in 2002 amid allegations of vote-rigging, intimidation and fraud. The 2005 Zimbabwe parliamentary elections were held on March 31 and multiple claims of vote rigging, election fraud and intimidation were made by the MDC and Jonathan Moyo, calling for investigations into 32 of the 120 constituencies. Jonathan Moyo participated in the elections despite the allegations and won a seat as an independent member of Parliament.

General elections were again held in Zimbabwe on 30 March 2008. The official results required a runoff between Mugabe and Morgan Tsvangirai, the opposition leader, however the MDC challenged these results, claiming widespread election fraud by the Mugabe government. The runoff was scheduled for June 27, 2008. On 22 June, however, citing the continuing unfairness of the process and refusing to participate in a "violent, illegitimate sham of an election process", Tsvangirai pulled out of the presidential run-off, effectively handing victory to Mugabe.

The MDC-T led by Morgan Tsvangirai is now the largest parliamentary party. The MDC was split into two factions. One faction (MDC-M), now led by Arthur Mutambara contested the elections to the Senate, while the other, led by Morgan Tsvangirai, opposed to contesting the elections, stating that participation in a rigged election is tantamount to endorsing Mugabe's claim that past elections were free and fair. However, the opposition parties have resumed participation in national and local elections as recently as 2006. The two MDC camps had their congresses in 2006 with Morgan Tsvangirai being elected to lead MDC-T, which has become more popular than the other group. Mutambara, a robotics professor and former NASA robotics specialist has replaced Welshman Ncube who was the interim leader of MDC-M after the split. Morgan Tsvangirai did not participate in the Senate elections, while the Mutambara faction participated and won five seats in the senate. The Mutambara formation has however been weakened by defections from MPs and individuals who are disillusioned by their manifesto. As of 2008, the Movement for Democratic Change has become the most popular, with crowds as large as 20,000 attending their rallies as compared to between 500–5,000 for the other formation.

On 28 April 2008, Tsvangirai and Mutambara announced at a joint news conference in Johannesburg that the two MDC formations were cooperating, enabling the MDC to have a clear parliamentary majority. Tsvangirai said that Mugabe could not remain President without a parliamentary majority. On the same day, Silaigwana announced that the recounts for the final five constituencies had been completed, that the results were being collated and that they would be published on 29 April. In mid-September, 2008, after protracted negotiations overseen by the leaders of South Africa and Mozambique, Mugabe and Tsvangirai signed a power-sharing deal which would see Mugabe retain control over the army. Donor nations have adopted a 'wait-and-see' attitude, wanting to see real change being brought about by this merger before committing themselves to funding rebuilding efforts, which are estimated to take at least five years. On 11 February 2009 Tsvangirai was sworn in as Prime Minister by President Mugabe.

In November, 2008, the government of Zimbabwe spent $7.3 million donated by the Global Fund to Fight AIDS, Tuberculosis and Malaria. A representative of the organization declined to speculate on how the money was spent, except that it was not for the intended purpose, and the government has failed to honor requests to return the money.
