A mother today demanded an investigation into pollution levels on a busy road after her nine-year-old daughter died from an asthma attack.
Ella Kissi-Debrah, who lived yards from the South Circular Road at Hither Green in south London, suffered a fatal attack in February 2013.
Mum Rosamund Kissi-Debra has asked a leading human rights lawyer to press for a new inquest into Ella's death.
She told BBC Radio 4 Today her daughter began to suffer a series of chronic attacks three years before she died.
The outcome of a new inquest could lead to the government being sued for a breach of human rights laws.
Lawyer Jocelyn Cockburn claimed the authorities failed to investigate links between Ella's death and pollution.
