The trial of a man accused of killing David Joslin, who intervened to stop a fight over five years ago, will start today. 

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 2009. 

Despite several police appeals, arrests 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, 34, of Poundfield Road, Loughton, had been summonsed to court accused of manslaughter.

Oliver denied manslaughter at Southwark Crown Court on February 10.

The trial starting today at the same 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.
