A man has pleaded not guilty to the manslaughter of a 'peacemaker' who was killed after he intervened to stop a fight.  

David Joslin, 23, died a week after being knocked unconscious by a single punch in Old Church Road, Chingford, during the early hours of December 20.  

Despite several police appeals and key witnesses on the night, no-one has ever been convicted of Mr Joslin's death. 

In October 2014, the Crown Prosecution Service (CPS) announced Michael Oliver, 33, of Poundfield Road, Loughton, had been summonsed to court accused of manslaughter. 

Appearing this morning at Southwark Crown Court, Oliver denied manslaughter and has been released on conditional bail to stand trial on June 15. 

The trial at Southwark Crown Court is estimated to last 10 days. 

Mr Joslin had been at a Christmas work party when he intervened to stop the fight between a group from the Obelisk pub and three men and a woman outside the jewellers Strictly Silver.

An inquest into Mr Joslin's death in 2013 revealed failings by Whipps Cross University Hospital in Leytonstone, which initially wrongly treated Mr Joslin as a drunk before transferring him to the National Hospital for Neurology and Neurosurgery.
