Mr. Bukovsky spent his last years in Cambridge trying to salvage his reputation after he was criminally charged in Britain over pornographic images of children found on his computer.
He pleaded not guilty, and insisted to
The New York Times in 2016 that the images had been planted, probably as part of a
dirty tricks operation by Russia. But a British computer expert who testified at his trial in December that year said there was no evidence of tampering, and that Mr. Bukovsky had apparently downloaded the images himself.
The trial, at the Cambridge Crown Court, was suspended soon after it started when Mr. Bukovsky was taken to a hospital with bronchial pneumonia. A full hearing of the evidence against him never took place.
