Out and about with Greville Janner

Lord Janner steps out in London after being ruled ‘too ill’ with dementia to be interviewed by police over child sex claim

Earlier this month, amid growing pressure from alleged victims, Ms Saunders was warned that she should be called before a Commons committee to explain her decision not to put Lord Janner on trial.

Ms Saunders has previously admitted that Lord Janner should have been prosecuted on three separate occasions – in 1991, 2002 and 2007, but botched investigations each time meant he escaped a prosecution.

Lord Janner has been accused of preying on young boys at three Leicester care homes between 1969 and 1989.

A senior barrister has now been brought in to review the controversial decision not to charge Lord Janner over alleged child sex crimes.

The CPS announced that the unnamed QC had been hired to give an independent assessment of the case.

The barrister – who has had no previous involvement with the case – will decide whether or not it is in the public interest to charge the former Labour MP because of his illness.
