Thabo Mvuyelwa Mbeki (Xhosa pronunciation: [tʰaɓɔ mbɛːkʼi]; born 18 June 1942) is a South African politician who served nine years as the second post-apartheid President of South Africa from 14 June 1999 to 24 September 2008. On 20 September 2008, with about nine months left in his second term, Mbeki announced his resignation after being recalled by the National Executive Committee of the ANC, following a conclusion by judge C. R. Nicholson of improper interference in the National Prosecuting Authority (NPA), including the prosecution of Jacob Zuma for corruption. On 12 January 2009, the Supreme Court of Appeal unanimously overturned judge Nicholson's judgment but the resignation stood.
