London, England (October 29) - Zambian President Michael Sata died at a London hospital on Tuesday night after receiving treatment for an undisclosed illness. He was 77. Media sources said he died after a sudden onset of a heightened heart rate at King Edward V11 Hospital on Tuesday night.
"It is with a heavy heart that I announce the passing of our beloved president," Zambian cabinet secretary Roland Msiska said on national TV in Lusaka. "I urge you all to remain calm, united and peaceful during this very difficult period."
The president's wife and son were at his bedside when he died, a few days after celebrations marking his country's 50th anniversary of Independence (October 24, 1964).
He is the second Zambian head of state to die in office after Levy Mwanawasa in 2008.
President Sata had not been seen in public for some time. It was common knowledge in Lusaka that he was unwell and had sought treatment overseas.
Vice-President Guy Scott - known as Zambia's most popular mzungu (whiteman) - has regularly stood in for President Sata at official events.
