Deputy Labour leader Harriet Harman has accused the Daily Mail of running a "politically-motivated smear campaign" against her.
The newspaper has reported that a group she used to work for had links to paedophile rights campaigners.
The National Council for Civil Liberties forged "close links" in the 1970s and 1980s to the Paedophile Information Exchange, the paper claimed.
Newsnight's chief correspondent Laura Kuenssberg spoke to Harriet Harman about the claims.
