Historical child abuse: Key investigations
"Lord Janner's case is one of 13 areas it will initially focus on. "
"Speaking at the first preliminary hearing, counsel to the inquiry Ben Emmerson QC said: "The allegations in summary are that Greville Janner exploited children and perpetrated a full range of sexual offences against them, including what would now be termed in English law as rape."
" `In relation to a number of the complainants it is alleged that Janner abused his position as an MP by arranging for children in whom he had a sexual interest to be brought to the Houses of Parliament.` "
"The offences are alleged to have taken place in children's homes and hotels between 1955 and 1988 - previously the oldest allegations to emerge against him dated back to the late 1960s."
"Wednesday's preliminary hearing was told that 17 complainants in the Janner case had been given core participant status in the inquiry, meaning they have the right to make statements, see documents and seek permission to ask questions."
"The inquiry has not received an application for core participant status from Lord Janner's family."
