the population, although according to critics such as Amnesty International, authorities have yet to properly substantiate their claims. On 29 March 2008, Zimbabwe held a presidential election along with a parliamentary election. The results of this election were withheld for two weeks, after which it was generally acknowledged that the Movement for Democratic Change – Tsvangirai (MDC-T) had achieved a majority of one seat in the lower house of parliament. On 10 July 2008, Russia and China vetoed UN sanctions on Zimbabwe pushed by the United Kingdom and the United States. The United States drafted the file, which would have placed an arms embargo on Mugabe's regime. However, nine of 15 countries on the UN Security Council opposed it, including Vietnam, South Africa and Libya, which argued that Zimbabwe was not a 'threat to international peace and security.' In late 2008, problems in Zimbabwe reached crisis proportions in the areas of living standards, public health (with a major cholera outbreak in December) and various basic affairs. During this period, NGOs took over from government as a primary provider of food during this period of food insecurity in Zimbabwe.

On 17 January 2013, Vice-president John Nkomo died of cancer at St Anne's Hospital, Harare, at the age of 78. A new constitution approved in the Zimbabwean constitutional referendum, 2013 curtails presidential powers. Mugabe was re-elected president in the July 2013 Zimbabwean general election which The Economist described as "rigged". and the Daily Telegraph as "stolen". The Movement for Democratic Change alleged massive fraud and tried to seek relief through the courts. In a surprising moment of candour at the ZANU–PF congress in December 2014, President Robert Mugabe accidentally let slip that the opposition had in fact won the contentious 2008
