Rotherham sex abuse survivor Sammy Woodhouse is demanding a probe into how disgraced Tory Imran Ahmad Khan became an MP.
Khan, 48, quit his Wakefield seat 11 days ago after being convicted of groping a 15 year old boy at a party in January 2008.
He is due to be sentenced at Southwark Crown Court later this month and has been warned he could face prison. He intends to appeal.
The court heard that the victim contacted the Conservative Party in 2019 after learning Khan was standing in the general election. He then called police after Khan was elected.
Now abuse campaigner Ms Woodhouse wants the Tories to launch an independent inquiry to find out why his warning was not acted on.
She said: “How can a major political party take a call off a victim saying he’d been abused as a child, do nothing, and then allow him to be an MP?”
“It’s gut wrenching and has broken the trust of survivors like me.”
The court heard that Khan forced the youngster to drink gin, dragged him upstairs and asked him to watch pornography before assaulting him.
Tories say they have no record of the complaint being made to them.
Now Ms Woodhouse, 36, is today (sun) launching a petition to put pressure on the party to start an investigation.
She added: “Their arrogant refusal to answer questions over this has left me questioning what they have to hide.”
Khan was appointed to an expert panel Ms Woodhouse also served on advising Home Secretary Priti Patel on how to deal with grooming gangs.
She played a key part in exposing the Rotherham child sex abuse scandal after revealing how she was groomed by gang leader Arshid Hussain at 14 and raped and beaten repeatedly by him.
The Sunday Mirror led the way in putting the scandal in the public eye as it emerged more than 1400 children were abused in Rotherham between 1997 and 2013. Hussain is new serving 35 years.
Sheffield Heeley Labour MP and shadow Transport Secretary Louise Haigh said: “The Tories have serious questions to answer over how they gave this criminal free rein to exploit his position.”
Staffordshire Police said: “We would like to commend the victim for reporting the offence committed against him.
“He has shown real bravery and courage in doing so.”
Before his trial Khan attempted to have the case heard in secrecy.
He argued that as an MP there were concerns about his safety and naming him in court would breach his human rights. He also wanted the victim’s age withheld.
