Oscar Pistorius is not mentally ill and can be held responsible for his actions, a psychiatric report has found.

However, his murder trial in Pretoria heard the results of the mental assessment may play a part in any future sentencing.

An expert panel had been assessing whether an anxiety disorder could have played a part in his actions when he shot dead his girlfriend Reeva Steenkamp.

The judge ordered the evaluation after a psychiatrist giving evidence in the athlete's defence told the court he suffered from generalised anxiety disorder, and that this may have influenced his judgement.

The tests were requested by the chief prosecutor and opposed by Pistorius' lawyer. The defence has now resumed with the doctor who amputated Pistorius' legs giving evidence.

Pistorius denies murder, claiming he mistook Ms. Steenkamp for an intruder.

The State prosecutor Gerrie Nel has read out the psychiatrists' conclusions.

Judge Thokozile Masipa ordered the athlete to undergo up to 30 days of tests from May 26th. The athlete attended Weskoppies Hospital in Pretoria, one of South Africa's top psychiatric institutions, every weekday until 4pm.

The ruling came after a psychiatrist giving evidence in the athlete's defence told the court he suffered from generalised anxiety disorder and that this may have influenced his judgement.

The tests were requested by the chief prosecutor and opposed by Pistorius' lawyer.
