Following his win, Sata appeared increasingly unwell and rumors about his rapidly failing health spread across Zambia. His spokesmen insisted that he was in good health, but his continuous absence at major state functions and events served to heighten concerns about his well-being. Sata was 77 years old when he eventually died of an undisclosed illness in a United Kingdom hospital on October 28th, 2014. He had held the office of the president for just a little over four years.
