A Somerset MP has raised concerns about the safety of data held for the government's new child register scheme.
ContactPoint will retain records of all 11 million children in the UK. It aims to provide a database to be used by those working in child protection.
Weston-super-Mare MP John Penrose said he was worried that the data collected in the project could be lost.
However Wansdyke MP Dan Norris, a former social worker, said the data was vital to safeguard children.
The information contained by ContactPoint will be accessible to at least 390,000 people nationwide, including health visitors and social workers.
It aims to provide a single point of contact to help avoid tragedies such as the Victoria Climbie and Baby Peter cases.
