 Zuma's victory in the election was partly due to the wide degree of support for him from the ANC Youth League, the South African Communist Party and the Congress of South African Trade Unions.Subsequent to this, in 2008 Zuma's ongoing corruption trial in relation to a multi-billion Rand arms deal was dismissed by the courts, which insinuated that Mbeki had unduly influenced the investigation into Zuma.In light of the court's findings, the ANC's National Executive Committee asked Mbeki to resign as president of the country, which he duly did on 20 September 2008.
