Archie Battersbee's life support will be switched off at 11am today, his family have been told.
The 12-year-old's parents lost a Supreme Court bid today to delay the withdrawal of his life-sustaining treatment pending a review of his case by a UN committee.
Christian Concern, who have been supporting the legal action by Archie's parents, said the Royal London Hospital had given the family until 9am to submit an application with the European Convention on Human Rights, otherwise the 11am deadline will be honoured.
