Inquest on Air?

It will be a landmark decision, if the inquest of 9 year-old Ella Kissi-Debrah rules that 'toxic' levels of atmospheric nitrogen dioxide were a factor in her death, in 2013. ( https://www.theguardian.com/environment/2020/nov/30/landmark-inquest-to-rule-if-air-pollution-killed-london-pupil). Ella was asthmatic and lived near London's South Circular road. It is clear that the levels of this pollutant from vehicular exhausts, exceeded legal limits. The UK government had signed up to 'safe' values of air pollution. If the coroner decides the gas played a role, ministers (and others?) might well be accountable.
