A coroner has ruled the death of Britain's first victim of the Neknominate drinking game as accidental.

Isaac Richardson, 20, collapsed and died after he drank 1.5 litres of spirits and wine at the Hostel Ordnance in Woolwich while making a Neknominate video.

His mother, Melissa Richardson told Southwark Coroner's Court she did not blame anyone for his death.

"I don't blame his friend who nominated him or the friends who were with him that evening. I know that they did try to help him.

"We feel very strongly that it is no one's fault and he would not have wanted anyone to be singled out."

A pathology report revealed he died of acute alcohol intoxication on 9 February and had drunk such a high amount of alcohol it was enough "to induce a coma".

Coroner Dr Andrew Harris praised his mother's "courage and objectivity" for not attributing any blame to anyone and recorded a verdict of accidental death.

He said: "Isaac died as a result of acute alcohol intoxication, he had no intention to end his life, he's accepted this challenge and we've heard from others that he was in a happy state of mind."

Neknominate was a popular craze at the beginning of 2014 in which people nominated one another to drink something and then post the footage online.
