The mother of an Oxford schoolgirl who died after taking almost pure MDMA has called for the drug to be legalised and regulated.
Martha Fernback suffered a cardiac arrest on 20 July 2013, after swallowing half a gram of 91% pure MDMA powder in the city's Hinksey Park.
Anne-Marie Cockburn urged politicians to change UK drug policy after the inquest recorded a verdict of accidental death.
