Alleged child sex abuse victims of Greville Janner have been barred from giving live evidence to the public inquiry into the former Labour MP.
Allegations against the late lord will be probed by the Independent Inquiry into Child Sexual Abuse next month.
But chairwoman Professor Alexis Jay ruled: “Having carefully considered… I have decided that no complainant evidence should be called.”
Ms Jay said the hearings must not become a “proxy trial”, in which complainants’ accounts of abuse are scrutinised and challenged with “no subsequent resolution”.
Lord Janner of Braunstone died in 2015 while awaiting trial on charges that he sexually abused children, many of whom had been residents at care homes in and around Leicester.
He had been investigated by police a number of times but was not charged until shortly before his death.
In 1992 the head of a public inquiry colluded with Janner by allowing him to cover up child abuse claims. Janner was quizzed about his relationship with a boy in a private hearing of a probe into children’s homes abuse.
He lied to reporters that he had not faced that line of questioning and transcripts show inquiry chief Andrew Kirkwood QC gave the lies his blessing.
Janner was charged with 22 offences dating back to the 1960s.
His family deny the allegations.
An inquiry spokesman said: “It is wrong to suggest complainant core participants have been banned from giving evidence to the Inquiry.
“The Chair has invited any who wish to do so to provide a written statement and summaries will be read into evidence.”
