The government was furious about the report and demanded the BBC reveal its source. The public broadcaster refused but Kelly told his MoD employers he believed he might have provided the information for the report.
As a result, he was dragged into the public eye and grilled by a committee of politicians about his relationship with journalists. Two days later, Kelly, 59, slit his wrist in a wood near his home.
Janice Kelly told the inquiry that her husband had received assurances from senior MoD officials that when he came forward, his name would not be made public.
Days later, however, the MoD press office confirmed his name to journalists.
Janice Kelly, 58, said her husband, a former United Nations weapons inspector who had made dozens of trips to Iraq, was also dismayed that the MoD described him as a middle ranking official or a junior.
"He was deeply, deeply hurt. He was being treated rather like a fly, I think that was the phrase he used," she said.
She said he was in torment in the days before and after his televised grilling at the hands of the parliamentary committee.
"I'd never known him to be as unhappy as he was then", Kelly, speaking via videolink, told the inquiry at the Royal Courts of Justice.
Speaking about the morning of the day on which Kelly killed himself, she said: "I was physically sick several times at this stage because he looked so desperate. He looked distracted and dejected. I just thought he had a broken heart.
"He looked as though he had shrunk, but I had no idea at that stage of what he might do later.
The inquiry under judge Lord Hutton is a key test for Blair, whose public trust ratings have plunged over the handling of Kelly's death and the failure to find banned weapons in Iraq.
The inquiry has heard no evidence to suggest the BBC's allegation of exaggeration was correct, but it has raised serious questions about the way the government dealt with the furore which followed.
