Nationalist MPs are to raise questions about the proceeds of loyalist murderer Michael Stone's new book in the House of Commons.
The revelation comes after high-profile coverage of the Milltown mass murderer's new book was last night labelled "unnecessary and distasteful".
The SDLP's Alasdair McDonn-ell said the publicity surrounding Stone's book, None Shall Divide Us, was reigniting the hurt for the families of the UDA man's victims.
Stone was convicted of six murders in the 1980s including the killing of three people at Belfast's Milltown Cemetery in March 1988.
Dr McDonnell has called for a tightening of the laws to ensure that paramilitary killers cannot profit in any way from selling their stories.
He made the comments after a Sunday newspaper yesterday carried eight pages of extracts from Stone's book. Among the fresh revelations made by Stone are claims that he colluded with RUC officers in the planning of the Milltown attack.
He claims that an RUC man drove him from Coleraine to Belfast with the weapons, guaranteeing his safe passage through vehicle checkpoints.
Stone also claims that his pistol and ammunition were RUC issue and that he was told that there would be no security presence at the funerals.
He says that while he was being interrogated after the attack, RUC officers asked him to sign autographs.
The book and its revelations are expected to attract a storm of outrage.
Dr McDonnell said he was deeply concerned at attempts to "glamorise" murderers.
The South Belfast representative said he would be asking SDLP MPs to raise the issue in the Commons this week.
"I am deeply concerned that these guys who earn their stripes as paramilitary killers are making a profit out of the pain and misery of others," Dr McDonnell said.
"People who have suffered at the hands of Michael Stone find it difficult enough to cope with what he has done but this sort of coverage simply reignites their hurt."
Dr McDonnell was also sceptical about Stone's apology to the families of his victims.
"I welcome any apology or retraction but doing it in the context of a propaganda effort is perhaps a bit disingenuous and flawed," he said.
