The manager of a Swansea Valley coal mine where four men died has taken to the stand to give evidence in his defence.
The miners drowned when the Gleision colliery flooded nearly three years ago.
Malcolm Fyfield, who managed to escape the disaster, denies four counts of manslaughter through gross negligence.
Cemlyn Davies was in court.
