"I have been in public life for 30 years and all of those years have been about protecting the vulnerable, protecting women and children," Harriet Harman insisted today.
"That's why I find it so unfair and offensive that the Daily Mail should put smear and innuendo on me as if somehow I supported those people that all my public life I've been fighting against.
"I think they are wrong to be doing that and that's why I'm speaking out."
"It's actually not me that should be apologising for something that I haven't done - it's the Mail that should be apologising for their smear and innuendo," Harriet Harman said today.
"I'm not going to apologise because I've got nothing to apologise for," Harriet Harman said today.
"I very much regret that this vile organisation, PIE, ever existed, and that is ever had anything to do with NCCL but it did not affect my work at NCCL - they had been pushed to the margins before I actually went to NCCL."
She went on: "To allege that I was involved in collusion with paedophilia or aplogising for paedophilia is quite wrong and is a smear."
Labour deputy leader Harriet Harman hit out at the Daily Mail newspaper today, after they attempted to "smear" her "by way of guilt of association" over the affiliation between a group she worked with in the 1970s and their links to a paedophile rights group. Writing on Twitter, she said:
The Camberwell and Peckham MP posted a picture of a Daily Mail article based around pictures of teen television personality Courtney Stodden photographed in her bikini as a 12-year-old child.
Harriet Harman has expressed "regret" over the links between a 1970s paedophile rights campaign and the civil rights organisation for which she once worked.
In a fresh statement this morning, a spokeswoman for Ms Harman said:
Labour leader Ed Miliband heaped praise on Harriet Harman yesterday, insisting he did not "set any store" by the claims made by the Daily Mail.
"I know she has a long and proud record of being on the right side of all of these issues," he said.
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.
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."
