The Documentary’s Core Story
Veteran journalist Jon Snow, 78, publicly disclosed his Alzheimer’s diagnosis and, with his wife Dr Precious Lunga, investigated a Chinese-owned copper-mine dam burst in Zambia. The investigation forms the centerpiece of Channel 4’s 90-minute film *Jon Snow: A Last Big Story*, released 20 June 2026.
Background and Timeline
Snow spent 32 years anchoring Channel 4 News (1989-2021) before retiring. He received an Alzheimer’s diagnosis in 2023, which he announced publicly in May 2026. While on safari near Victoria Falls earlier in 2026, he learned of the dam failure, prompting the documentary’s investigation.
Key Figures
Key participants include Jon Snow, the veteran Channel 4 anchor; Dr Precious Lunga, his epidemiologist wife and co-investigator; Ben de Pear, Snow’s former Channel 4 editor who provided editorial guidance; and Zambian community leaders who supplied eyewitness testimony.
Impact and Significance
The NHS estimates Alzheimer’s affects roughly one million UK residents. By pairing personal health advocacy with investigative reporting, the film aims to reduce disease stigma while exposing a chemical spill that destroyed farmland and contaminated water for Zambian communities, a disaster previously omitted from international news. The film also highlights the broader challenge of reporting on environmental crimes in regions where authorities have downplayed incidents, underscoring the role of independent journalism in holding multinational corporations accountable.
Official Statements & Responses
Channel 4 said the documentary, produced with the Alzheimer’s Society, offers a “poignant insight into dementia and a call for redress for Zambians.” The Alzheimer’s Society welcomed the film’s awareness-raising role. NHS guidance cited in the programme advises prompt review for rapidly worsening symptoms.
Criticism & Opposition
Snow’s interviews uncovered a cover-up by Zambian authorities who downplayed the dam breach, and whistle-blowers noted the incident received almost no media attention before his investigation, highlighting institutional resistance to transparency.
On-the-Ground Reports
Snow and Lunga recorded testimonies from villagers describing polluted water and loss of crops.
