The Home Office was warned that Lord Janner was abusing young boys two decades ago but did nothing about it . The Home Office was warned that Lord Janner was abusing young boys two decades ago but did nothing about it. An MP passed a dossier of information to the department in the hope it would kick-start a fresh police investigation. But instead the paperwork was shelved by officials until it was discovered in 2013 and belatedly passed to Leicestershire Police. The revelation will heighten fears that the peer, now 86, was the beneficiary of an Establishment cover-up. The missed opportunity to bring him to justice echoes the case of the late paedophile Liberal MP Cyril Smith who continued in public life despite repeated warnings of his crimes. It heaps pressure on the Home Office to reveal exactly who knew what and when about the disturbing allegations against Janner. Last night Labour’s Simon Danczuk – who outed Smith as a predatory child abuser – called on the department to ‘come clean’. ‘The Director of Public Prosecutions has admitted there were previously missed opportunities to investigate Lord Janner,’ he said. ‘The Home Office needs to come clean on what information was passed to officials in 1995. ‘This scandal is getting worse every day and the public are rightly angry at the shambolic way this case has been handled.’ Director of Public Prosecutions Alison Saunders sparked fury earlier this month when she said Janner could face 22 charges but his health is too poor to put him on trial. She said that the former Leicester MP was investigated in 1991, 2002 and 2006 but mistakes meant he was never charged. Now the Daily Mail can reveal a fourth opportunity was missed when an unnamed MP passed a dossier to the Home Office in 1995. The politician received a letter linking Janner to prolific paedophile Frank Beck, who died in jail the previous year. Beck was jailed in 1991 for abusing children after a trial in which Janner was named by a victim, prompting him to proclaim his innocence in the Commons. The MP expected the 11 pages of detailed notes, which also identified several other suspects, to be passed to police. But nothing was done until it was uncovered during a review of Home Office archives in 2013. Labour MP Simon Danczuk is calling for the Home Office to 'come clean' over the dossier. The Director of Public Prosecutions Alison Saunders earlier sparked fury by saying Lord Janner could face 22 charges . Lord Janner’s £2million home was transferred to his three children by someone holding power of attorney, officials have confirmed. The apartment near Hampstead Heath in North London was signed over free of charge in March last year – the same month police raided his Westminster office and three months after they searched his home. The apartment is likely to have been Janner’s most valuable asset, and the revelation raises questions about whether the Labour grandee – who was diagnosed with Alzheimer’s in 2009 – and his family planned for the possibility of being sued by his alleged victims. In 2013, paedophile BBC presenter Stuart Hall signed over the deeds of his £2million mansion to his wife just before he was jailed. He then offered his victims as little as £2,000 compensation. Home Secretary Theresa May ordered the review over fears her department was holding evidence of historic child abuse by influential people. A trawl through more than 700,000 documents identified four ‘items’ that should be passed to police. In a heavily censored report, one document involved the paedophile ring led by Beck which preyed on vulnerable children at Leicestershire care homes. It stated: ‘Allegations from XX that XX could have been involved in the child abuse along with convicted paedophile Frank Beck. The writer… also claimed that some police investigations had already taken place but there is no evidence that the Home Office passed the complete information to police.’ Michael Howard was Home Secretary when the MP sent the letter warning about Janner to his department. A spokesman for the former Tory leader, who is now a peer, said he had ‘no recollection’ of seeing the dossier but believes such material should have been forwarded to police. Soon after the publication of the Theresa May review, a second, more in-depth report homed in on allegations against Janner in August 2014. Conducted by NSPCC chief executive Peter Wanless, it specifically asked Government departments to search their archives for mentions of ‘Greville Janner’. When the report was published in November it revealed a file on Janner was among 114 dossiers on child sex abuse that went missing from the Home Office. Last night, the Home Office highlighted how both reviews did not directly accuse it of covering up information on child abuse.
