Unbiased summary
Jon Snow: A Last Big Story is a Channel 4 documentary following former Channel 4 News anchor Jon Snow, 78, who was diagnosed with Alzheimer's disease after retiring in 2021. The film, made in conjunction with the Alzheimer's Society, was originally conceived as a dementia-awareness travelogue accompanying Snow and his wife, Dr Precious Lunga, a neurologist and neuroscientist, on a trip to Zambia. During the trip, Snow learned from a safari guide that a dam had collapsed at a copper mine owned by Sino-Metals Leach Zambia, spilling approximately 1.5 million tonnes of toxic material, poisoning rivers and devastating local communities. The disaster had received virtually no media coverage. Snow investigated the story, interviewing whistleblowers and uncovering evidence of a cover-up by Zambian authorities. The documentary interweaves this investigation with footage of Snow's storied career and scenes documenting the progressive cognitive effects of his Alzheimer's diagnosis.

Angle
The Guardian frames the documentary as a literary and emotional meditation on memory, identity, and decline, foregrounding Snow's Alzheimer's experience and his wife's emotional burden above the journalistic investigation.
Bias
The Guardian leads with Snow's cognitive decline in considerable clinical and emotional detail, including the doctor's appointment and memory test failures, giving this more prominence than the mining story itself. The environmental disaster and corporate wrongdoing are mentioned but relatively subordinated to the human-interest and caregiver narrative. The piece adopts a literary, elegiac tone that editorialises the subject warmly, which, while not factually inaccurate, is clearly a deliberate framing choice that prioritises pathos over journalistic content.
Angle
The i Paper presents a broadly balanced profile that celebrates Snow's journalistic legacy while giving roughly equal weight to the Alzheimer's storyline and the environmental investigation.
Bias
The i Paper is the most balanced of the three, covering both the dementia narrative and the mining disaster investigation with reasonable parity and factual accuracy. It does editorially celebrate Snow's character and career with admiring quotes from colleagues, which adds a slightly hagiographic tone, but this does not significantly distort the facts. The observation that Lunga supports Snow's investigation because 'it's vital for him to keep active' adds context not prominently featured elsewhere, though this framing slightly medicalises his journalistic motivation.
