The family of murdered schoolgirl April Jones have started a petition calling for all sex offenders to remain on the register for life.
The family hope to gather 100,000 signatures backing April's Law, after the author of a previous petition proved impossible to track down.
Five-year-old April was murdered by paedophile Mark Bridger after being abducted from outside her home in Machynlleth in October 2012.
Before the abduction, Bridger, who had more than 500 indecent images of children on his computer, had been looking at horrific child pornography.
Three years ago, the previous petition received more than 70,000 signatures.
The new petition needs 100,000 signatures before it can possibly be discussed in Parliament at Westminster, but the family hope the 70,000 original signatories will also sign it.
In 2013, the Jones family met with Prime Minister David Cameron and Sara Payne, whose eight-year-old daughter Sarah was killed by Roy Whiting in 2000.
Coral said they are disappointed that, in the years since, "nothing more has been done".
Sarah's Law came into being in 2011, allowing parents and guardians to ask the police to tell them if someone has a record for child sexual offences.
The NSPCC says sex offenders should remain on the register until it is decided they no longer pose a threat to children.
