The consultant editor of the Daily Mail newspaper has reiterated his demand for an apology from Labour's Harriet Harman over The National Council for Civil Liberties' "affiliation" to the now-defunct Paedophile Information Exchange in the 1970s.
Appearing on Daybreak, Andrew Pierce said: "How difficult can it have been to oust a disgusting organisation like that?"
In a Newsnight interview last night, Harriet Harman denied supporting or being influenced by PIE: "It is not the case that my work, when I was at NCCL, was influenced by PIE, was apologising for paedophilia or colluding with paedophilia," she said.
Labour deputy leader Harriet Harman has insisted her work has always been to protect children from child abuse, as she accused the Daily Mail of running a "politically-motivated smear campaign" against her.
The newspaper published claims that the National Council for Civil Liberties (NCCL), a group Harman used to work for, had alleged historic links to a paedophile rights campaign.
In her first interview since the Mail published the allegations, Ms Harman told BBC2's Newsnight: "It is not the case that my work, when I was at NCCL, was influenced by PIE [Paedophile Information Exchange], was apologising for paedophilia or colluding with paedophilia.
"That is an unfair inference and a smear.
"My work has always been, when I was at NCCL and when I have been in politics and ministerial office, to protect children, especially from child abuse."
Deputy Labour leader Harriet Harman was accused of issuing a denial "full of pedantry and obfuscation" by the newspaper that made allegations about her historic involvement in paedophile rights campaigns.
The Daily Mail claimed the shadow culture secretary has failed to answer the main charges it has levelled against her in a series of articles and has instead denied allegations it has not made.
It follows Ms Harman's decision to release a detailed statement accusing the newspaper of a "politically-motivated smear campaign".
A Daily Mail spokesman said: "The belated statements today of Ms Harman and her husband - full of pedantry and obfuscation - failed to answer the Mail's central points and deny allegations the Mail has not made.
"More pertinently they have failed to utter a word of contrition or sorrow about The National Council for Civil Liberties' closeness to the notorious Paedophile Information Exchange, anorganisation that validated the activities of a monster like Jimmy Savile.
"Nor do they utter a word of apology to the victims of PIE."
The Daily Mail have attempted to smear Harriet Harman "by way of guilt of association", the Labour Deputy leader has claimed in a statement.
The editor and proprietor of the Daily Mail are entitled to their political views and they are of course entitled to oppose what I stand for but they are not entitled to use their newspaper to smear me with innuendo because they disagree with me politically and hate my values.
– Harriet Harman, Labour Deputy Leader
Given the seriousness and the aggression with which the Daily Mail are pursuing me, I feel that I need to put the facts in the public domain.
– Harriet Harman, Labour Deputy Leader
Commenting on an allegation that she supported the lowering of the age of consent to 10, she said:"This is not true.
"I supported the equalisation of the age of consent (as set out in the National Council for Civil Liberties document "priorities and strategy for the executive committee June 1981") by making the age of consent the same for homosexual as well as for heterosexual sex."
Labour's deputy leader Harriet Harman has denied claims from the Daily Mail that she supported lowering the age of consent to 10, scrapping the law on incest, or sought to water down the law on child pornography.
"They have accused me of being an apologist for child sex abuse, of supporting a vile paedophile organisation, of having a relaxed attitude to paedophilia and of watering down child pornography laws. These are horrific allegations and I strongly deny them all of them," she said in a statement.
Mrs Harman and her MP husband Jack Dromey broke their silence after the newspaper ran a series of stories about their actions while officials at the National Council for Civil Liberties (NCCL) in the 1970s.
The body granted 'affiliate' status to the Paedophile Information Exchange (PIE), and is said to have lobbied for loosening of laws. Former health secretary Patricia Hewitt, who was also involved in the NCCL, has also faced accusations, but not commented.
Labour deputy leader Harriet Harman has called Nick Clegg's response to the allegations against Lord Rennard "a cop out" and claimed the women who made the complaints are "being hung out to dry".
Ms Harman said: "The Lib Dem women who complained about Lord Rennard did a brave thing in coming forward and making an official complaint. But now they are being hung out to dry and accused of suffering from 'distress'.
"They have complained about inappropriate behaviour but Clegg says unless proved beyond reasonable doubt - ie that Rennard committed a criminal offence - the Lib Dems can take no action. This is a cop out.
"Nick Clegg must get off the fence otherwise it will send out a signal to any woman who suffers sexual harassment that she needn't bother to complain."
