Archie died at 12.15pm local time at the Royal London Hospital, hours after doctors stopped the ventilator keeping him alive, Dance told reporters, adding she was “so proud to be his mum”.
“Such a beautiful little boy, and he fought to the end,” she said.
Dance said the hospital had made it clear there were no other options and that life support would be withdrawn Saturday morning.
The 12-year-old had been in a coma since being found unconscious by Dance’s mother in April. He was kept alive by a combination of medical interventions, including ventilation and drug treatments, according to Britain’s PA news agency.
Doctors eventually concluded the boy was “brain dead,” prompting his family to continue a legal battle to keep him on life support in the hope he would recover, the PA reported.
In recent days, the family has made bids to the Supreme Court, the Court of Appeal and the European Court of Human Rights to have him transferred to a hospice to die, according to the PA.
“Members of his family were present at his bedside and our thoughts and deepest condolences remain with them at this difficult time,” the statement added.
