Ms Adoo-Kissi-Debrah said: “I have been fighting for justice for Ella for over 14 years. Firstly, to find out what was making her so severely ill, and secondly to raise awareness about the dangers of air pollution.
“Nothing will ever make up for the pain and suffering that Ella went through, or for the trauma of losing a beloved daughter and sister at such a young age.
“The loss to our family is immeasurable.”
Accompanied by Ella’s siblings, Ms Adoo-Kissi-Debrah met Emma Hardy, a minister in the Department for Environment, Food and Rural Affairs (Defra) on Thursday morning.
“I have told Ms Hardy today that so much more needs to be urgently done to improve our air quality and that I stand ready to assist her and the government to tackle what has become a public health crisis,” she said.
Ms Adoo-Kissi-Debrah has urged the government to introduce “Ella’s Law”, which she wants to include the “right to breathe clean air as a basic human right”, among other measures.
