A review into how the Home Office handled historic child sex abuse allegations at Westminster in the 1980s has reportedly been unable to uncover any of the crucial missing files that prompted the investigation.
The BBC reports that the so-called 'Dickens Dossier', handed to the Home Office by former Tory MP Geoffrey Dickens, has not been found.
Labour MP John Mann said he was concerned that civil servants who dealt with a dossier related to child abuse at the time had not come forward to give evidence to NSPCC chief Peter Wanless, because they are forbidden to reveal information about it by the Official Secrets Act.
Mr Mann told BBC Radio 4's Today programme:
As Fiona Woolf becomes the second person to quit as head of the Westminster sex abuse probe, here is what you need to know about it so far.
The chair of an inquiry into an alleged historical Westminster paedophile ring has been accused of 'editing' details of her impartiality.
