A Yorkshire man accused of killing a workmate with a single punch after they argued about football in a Halesowen pub has told a jury he acted in self defence.

30 year-old Dean Hartley broke the jaw of Karl Swift and he was unconscious when his skull was badly fractured as he hit the pavement.

Hartley claimed it was a reaction because he thought he was going to be hit. The two men had been drinking with colleagues in the William Shenstone pub before the incident.

Hartley has denied manslaughter and his trial at Wolverhampton Crown Court is continuing.
