A bereaved mother is calling for social media firms to hand over children's data "now, before it's too late".
Ellen Roome, 48, from Cheltenham in Gloucestershire said she might never understand why her 14-year-old son Jools Sweeney took his own life three years ago.
MPs could agree on Wednesday that tech giants must hand over children's data to parents if their child has died as Max Wilkinson, the MP for Cheltenham in Gloucestershire, has proposed an amendment to the Government's Data Bill.
"If they've still got the chance to change it now, I want the Data Bill changed so that this is in there and we don't have to wait years for a new law to go through," Ms Roome said.
Jools died in April 2022, and Ms Roome believes his death could have been linked to an online challenge gone wrong.
She said if social media companies gave bereaved parents access to their child's data and a harmful trend had a role to play in their death, parents and coroners could "stop it happening to other children".
"If we've got a chance to change it, we need to do it now, before it's too late," she said.
