A nine-year-old girl who had a fatal asthma attack may become the first person in the UK to have air pollution listed as their cause of death, as a fresh inquest is granted by the High Court.

Ella Kissi-Debrah, who lived 25 metres from the South Circular Road in Lewisham - one of London's busiest roads - died in 2013 after suffering seizures for three years.

An inquest in 2014 concluded her death was caused by acute respiratory failure and severe asthma.

But Ella's mother Rosamund campaigned for a second inquest to determine whether air pollution near their home was a contributing factor.

The child was first taken to hospital in 2010 after suffering a coughing fit and was admitted a further 27 times.

A report last year by Professor Stephen Holgate found that air pollution levels at a monitoring station just a mile from Ella's home “consistently” exceeded lawful EU limits during the three years before her death.
