It has since emerged that Janner, who was diagnosed with Alzheimer’s disease in 2009, used his own car and his own Lords security pass to attend the Houses of Parliament on official business as recently as last June, months after his lawyers told police that he was too sick to be questioned over the alleged sex attacks.

One of Janner’s alleged victims, Paul Miller, 53, said he had been hand-picked by the politician for a trip to London. At the time, Greville Janner was a Leicester MP and Miller was a 9-year-old who lived in an orphanage.

Miller has given a statement to police detailing the way he was treated. He described the events to The Sunday Express: “Janner met us outside the Commons and gave us all a guided tour of the place. I was enthralled until he pounced on me in the chapel.”

Now a father who has battled depression and alcoholism, Miller said he was too scared to tell staff about the attack at the time. Now that he is willing to speak out, it seems his fears about being ignored were well-founded.
