Archie Battersbee's mum has vowed to continue fighting for "justice" a year after her son was found unconscious at their home in Southend, Essex.
Hollie Dance found her 12-year-old son unresponsive on April 7 last year. He died four months later in hospital after his parents lost a legal battle with medics over the withdrawal of his life support.
Ms Dance, who failed to persuade appeal judges to overturn the ruling, has since asked the United Nations Committee on the Rights of Persons with Disabilities to consider Archie's case.
