A petition has been launched requesting another inquest after a 9-year-old Hither Green girl's death was attributed to "air pollution".

Rosamund Kissi-Debrah was living in Hither Green, close to the busy south circular, when her daughter Ella suddenly developed severe asthma.

The mum is now calling for a new inquest into her daughter's death after she says new evidence has emerged linking her death to illegal levels of air pollution.

She said: “I’ll never forget the day we lost Ella. It was in the early hours of the morning on the last day of term. She had already picked out her outfit for the end of term disco.

“But just a few hours later she suffered coughing fits followed by several seizures. She was hospitalised and we lost her. She never made it to the party.”

An inquest in 2014 into her unexpected death concluded that Ella died due to a severe asthma attack followed by a seizure, possibly caused by an allergic reaction to something in the air.

However the mother says an exact cause was never discovered.

“New medical research shows that Ella’s frequent hospital admissions were linked with spikes of illegal levels of air pollution around our home near the south circular road," she added.

She now wants help to pile on the pressure and call for the government to finally make the change and get London air pollution back down to a safer level.
