It says Liverpudlians "wallow" in their "victim status", adding it is part of the "deeply unattractive psyche" of many in the city.
The article goes on to say Ken Bigley's brother Paul was wrong to say the prime minister has "blood on his hands".
It also says Mr Bigley took a risk by working in Iraq against the advice of the Foreign Office, and "his motives and misjudgements... should, without lessening sympathy for him and his family, temper the outpouring of sentimentality in which many have engaged for him".

The incident claimed the lives of 96 Liverpool football supporters.
The Hillsborough Family Support Group described the article as "typical Tory propaganda".
Phil Hammond, vice chairman of the group said: "Boris Johnson, he knows nothing about this.
