Mum's campaign to prevent texting at wheel after death of her son

The mother of a teenage cyclist - killed after a collision with a van - is calling on the Government to back a new phone app, designed to stop drivers from texting.

Daniel Squire was killed while cycling to Deal two years ago. A van driver was cleared of causing death by dangerous driving - despite admitting in court he'd been texting shortly before the accident.

Tracy Squire is supporting the app - which disables the mobile phone as soon as the driver gets into a car. Derek Johnson reports.
