The former victims minister has accused the government of failing to listen to the survivors of convicted sex offender Jeffrey Epstein.
Labour MP Alex Davies-Jones,who resigned in May, said victims have been treated as a "footnote" in the row over Lord Mandelson's appointment as ambassador to the US.
Speaking in the House of Commons, Davies-Jones also read out a statement from Lisa Phillips, a US survivor of Epstein, who accused Prime Minister Sir Keir Starmer of ignoring her requests for a meeting.
Cabinet Office Minister Darren Jones offered to meet the victims and apologised for "subconsciously" treating Lord Mandelson differently because of his power and influence within Labour.
The exchanges came during a Commons debate about the government's response to a motion forcing it to publish files related to Lord Mandelson's appointment.
The peer was sacked in September 2025after Downing Street said new information about the depth of his relationship with Epstein had emerged.
Sir Keir's decision came after he reviewed emails that showed Lord Mandelson sent supportive messages to Epstein as he faced charges for sex offences in 2008.
Davies-Jones said what struck her most "about this whole affair is not what has been said but what has been missing".
She told the Commons: "For all the headlines that have been generated by this story, the people whose lives were devastated by Jeffrey Epstein's abuse have too often been reduced to a footnote and that should concern every single one of us.
"Perhaps the most revealing aspect of these disclosures is not simply who ministers were meeting but who they were not."
Davies-Jones said while it appears that "significant effort" went into "cultivating relationships with influential figures in the tech world, victims were left feeling unheard and overlooked".
She added she was "forced to fight tooth and nail" while in the government to have the voices of victims heard, adding this showed "something is not working as it should" and led to her "difficult but necessary decision to resign".
Davies-Jones also said she had been asked by Phillips,a former model who has spoken out about her experiences as a survivor of Epstein, to read out a statement on her behalf.
MPs heard Phillips "struggles to understand" why Sir Keir appointed Lord Mandelson "when his association with Epstein had long been publicly known".
Phillips, who has called for a public inquiry, added: "I have repeatedly requested the opportunity to meet with the prime minister but those requests have all been ignored.
