The National Council for Civil Liberties was a very mainstream organisation at that time, the pre-cursor to Liberty, if you like.
Most people here actually think the idea that this horrible paedophile organisation was allowed to affiliate and that the NCCL had totally open affiliate policy is bonkers.
Quite lot of people in the Labour Party think it might have been better for Harriet Harman to just say "yes, that was crazy," to accept the deal and apologise and move on.
But as you see in my interview, she is clearly very upset about it.
She is upset because her point is: "I've spent my whole life campaigning for children, for women, for the dispossessed and here I am being accused of helping the very people I was fighting against all the time."
When it was question of Ed Miliband against The Daily Mail with the attack on Ed Miliband's father, there was emotion too, but there was an element of political calculation.
Ed Miliband wanted to be seen taking on the big newspaper organisations.
With this, I've got to say, it's pure emotion.
Political correspondent Carl Dinnen said Harriet Harman is not helped by the fact that Liberty, the organisation that formed from the NCCL, described links to the paedophile group as "a continuing source of horror and disgust."
Harriet Harman has repeatedly insisted that she had nothing to do with the NCCL's affiliation with PIE and that her work was never influenced by their campaigns.
"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."
