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: " For ten weeks now the Mail has repeatedly asked three leading Labour figures to answer questions about the involvement of the NCCL, a body in which they played leading roles, with a vile paedophile group whose actions are currently being investigated by the police.
"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 NCCL's closeness to the notorious Paedophile Information Exchange, an organisation that validated the activities of a monster like Jimmy Savile. Nor do they utter a word of apology to the victims of PIE."
