[2] He was associated with a number of Jewish organisations including the Board of Deputies of British Jews, of which he was chairman from 1978 to 1984, and was later prominent in the field of education about the Holocaust.

Criminal proceedings brought in 2015 were halted by his death in December of that year; claims made against his estate were all dropped by May 2017, with Janner's family calling the claimants "false accusers" afraid of cross-examination.

[3] Carl Beech, whose accusations had led to the Operation Midland police investigation (and who was himself found to be a child sex offender), was convicted for false accusation of Janner and others and jailed for 18 years;[4] the Janner family subsequently criticized both the Labour politician Tom Watson for his part in the affair, and the system "where people are believed instantly before the evidence is examined".

[6] In October 2021, the enquiry concluded that the police "appeared reluctant to fully investigate" the allegations against Janner, and that the process had been marred by a "series of failings".

[8] Janner and Ruth, his sister (later Lady Morris of Kenwood), were evacuated to Canada at the age of 11, because their parents anticipated a Nazi invasion of Britain.

[10] At the age of 18, he served in occupied Germany working for the War Crimes Investigation Unit of the British Army of the Rhine for 18 months.

[15] In parliament, and outside, he was involved in campaigning for the War Crimes Act 1991, lobbying the Thatcher government to allow legislation to bring those responsible for Nazi atrocities (and now resident in Britain) to justice.

[25] In the incident, which occurred during the 2006 Lebanon War, the two men had disagreed in the House of Lords chamber after Bramall had made comments Janner considered too critical of Israel.

Janner later sought the advice of fellow peers about how and whether to make a formal complaint against Lord Bramall, before deciding to accept an apology.

[29] In 1955, Janner married Myra Louise Sheink, who was originally from Australia and the niece of Sir Israel Brodie, the former Chief Rabbi of Great Britain and the Commonwealth.

[1][37] At a court hearing in August 2015, a medical specialist acting as a witness for the defence said that Janner was experiencing the early stages of Parkinson's disease.

After it was decided in 2015 that he should have been prosecuted earlier, the accusations were to be investigated in a "trial of the facts" in April 2016—Janner was deemed to be too ill for a criminal trial—but he died before this could happen, though his actions were included in a large inquiry into historical sex abuse.

In 1991, the director of a children's home in Leicestershire, Frank Beck, was convicted of child abuse over 13 years to 1986 and sentenced to five life terms.

[51] In 2013 and early 2014, Leicestershire Police searched Janner's home in north London and his offices in the House of Lords in connection with an enquiry linked to historical child abuse allegations.

[37] They decided that it failed the public interest test, as Janner was diagnosed with Alzheimer's disease in 2009 and the associated dementia had progressed to a point where he could not engage with the court process, and his evidence could not be relied upon.

[37][57] A retired High Court judge, Sir Richard Henriques, was appointed to carry out an independent investigation of all matters involving the CPS which related to the case.

[1] "Lord Janner is a man of great integrity and high repute with a long and unblemished record of public service", his family said in a statement issued at the time of the CPS decision in April 2015.

[46] Lord Macdonald, the former DPP, told the Today programme on BBC Radio 4 on 18 April that a decision over whether to prosecute Janner should have been taken in court by a judge, rather than by the CPS, to remove any doubt that the most recent investigation had been carried out properly.

John Mann, who was then campaigning to retain his Bassetlaw seat for Labour during the 2015 general election, told The Daily Telegraph that all the documents relating to the upper chamber's contact with Janner should be made public.

[55] On 29 April 2015, Dame Lowell Goddard, the New Zealand judge appointed to head the Independent Inquiry into Child Sexual Abuse, announced that she would also investigate the Janner case.

[66][67] In the new parliament elected on 7 May 2015, 78 MPs supported a reversal of the DPP (Alison Saunders') decision and for the case to go to court in a "trial of the facts".

[78] The presiding judge, Mr Justice Openshaw, summarised his decision based on the evidence from four medical experts: "The defendant has advanced and disabling dementia that has deteriorated and is irreversible, and accordingly I find that he is unfit to plead."

[84] In an interview with The Times, the Janner family declared, "Our father's reputation as a man who devoted his life to good has been restored."

His son, Daniel Janner, stated, "These false accusers, having dropped their claim because they risk being cross-examined, can no longer form the basis of this strand.

[82] The report of the retired High Court judge Sir Richard Henriques concerning the earlier investigations of allegations made against Janner was published in January 2016.

[85] The CPS and Leicestershire police were again criticised in his independent report, and he concluded that there had been sufficient evidence to make probable a successful prosecution of Janner in 1991, 2002 and 2007.

[87] The 2002 investigation was connected with allegations of historic abuse at a children's home, in which a former resident made accusations against Janner: "The failure to forward Complainant 2's statement to the CPS for charging advice is remarkable", Henriques wrote.

[58] The Independent Inquiry Into Child Sexual Abuse announced on 16 November 2016 that it was delaying its hearings into Janner due to a "significant overlap" between its investigation and the criminal proceedings, which could cause prejudice in court.

"[91][92] Janner's daughter, Rabbi Laura Janner-Klausner, said "We have a system where people are believed instantly before the evidence is examined instead of being listened to compassionately and the allegations properly investigated.

"[93] Janner-Klausner was criticised by Migdal Emunah, a charity which supports victims of sexual abuse in the Jewish community, for using her position as a senior rabbi to discredit the allegations against her father.
