A girl who stabbed two teachers and a fellow pupil in a playground has told a jury that she had taken knives into school since she was seven or eight.

The girl, who was 13 at the time of the attacks, said she carried blades every day because she used them to self-harm and she was frightened of being bullied and didn’t trust the system to protect her.
