Zambian President Michael Sata has died in London, where he had been receiving treatment for an undisclosed illness, the government said.
Roland Msiska, secretary to the Zambian Cabinet, said in a statement on Wednesday that Sata died late on Tuesday in London, where he was being treated.
"As you are aware the president was receiving medical attention in London," Msiska told state television.
"The head of state passed on in October 28. President Sata's demise is deeply regreted. The nation will be kept informed on burial arrangements."
Msiska says Sata's wife, Christine Kaseba, and other family members were with the 77-year-old president when he died.
