Zimbabwe’s President Robert Mugabe has been endorsed as leader of his ZANU-PF party for another five years, promising to resist opposition calls to reform the country’s security forces.The 85-year-old has been at the helm since independence in 1980. But ZANU-PF lost its majority in parliament for the first time last year and was forced into an uncomfortable power-sharing deal with the opposition Movement for Democratic Change, led by Morgan Tsvangirai. The MDC wants a shake-up of the security forces, claiming they are being used by ZANU-PF to put down dissent in Zimbabwe. At his party’s congress, Mugabe refused to entertain the idea of any change. The opposition also wants the attorney general and the central bank governor to be replaced. But ZANU-PF passed a resolution rejecting all the opposition demands.
