Kelly spoke to the journalist concerned and gave him some background info, no secrets.
When the row between the BBC and government broke out, Kelly told his bosses at the ministry of defence that he had talked to the journalist.
The government then released Kelly's name to the press, and tried to use him to discredit the BBC story, by pointing out he didn't tell the BBC the dossier was "sexed up"
Kelly was then questioned by a parliamentary committee, and has been repeatedly accused by government ministers of being the source for the story, even though Kelly himself denied it.
Kelly was apparently stressed, and his wife said he was upset when he went out yesterday. Reading between the lines, he killed himself.
