A woman from Staffordshire, whose soldier son was killed in Iraq, has accused Gordon Brown of evading the questions in his evidence to the Chilcot Inquiry.
Susan Smith's son, Private Phillip Hewett, 21, died when his lightly armoured Snatch Land Rover was blown up in Al Amarah in July 2005.
Mrs Smith, from Tamworth, has campaigned to discover why more money was not spent on Army equipment so her son could have travelled in a more heavily armoured vehicle.
She watched Mr Brown give his evidence inside the inquiry chamber at the Queen Elizabeth II Conference Centre in Westminster, central London.
But she was not impressed by the Prime Minister's responses to the questions put to him by the five members of the inquiry panel.
"To be honest, I found it very hard work because they never seem to answer anything," she said. "He goes all around the world and we're no further forward than we were when we started.
"It becomes hard work trying to find an answer in his answers - I'm struggling to find some substance in there, and there isn't any.
"He's saying there's this much money here and there was that much money there. But he's not actually answering anything."
Mrs Smith was also sceptical about Mr Brown's expression of sadness for the deaths of the 179 British personnel killed in the Iraq conflict.
"To be honest, I just get a feeling that some of it is spin. I imagine he's genuinely sorry, but is it for political reasons that he said it?"
