A mentally ill British man has admitted to killing his mother in Portugal by battering her, slitting her throat, defiling her body and dousing it in acid.
Louis Yates, 31, confessed in a Portuguese courtroom today to killing his mother Christine, 68, at their £1.7million home in the Algarve in August last year.
While high on drugs he had thought of himself as Jesus, saw his mother as the devil and believed the CIA had ordered him to hit her 'as hard as he could'.
Yates, who suffers from paranoia and schizophrenia, is likely to be confined in a high-security hospital as prosecutors accept he cannot be held criminally responsible.

Cheltenham-born Yates was led into the Portimao courtroom in handcuffs today for the start of his murder trial.
Accepting his mother was not the devil, he voiced regret for the killing and said: 'It's terrible. For many years she was my best friend.'
Prosecutors say he battered his mother at the home in Caramujeira, near Lagoa, on August 4, 2018, before taking a saw and a kitchen knife to cut her throat.
He then defiled her and poured acid over her body, it is claimed.
The court heard he stamped on her head and upper body and dragging her from her bedroom where he attacked her to an outside patio where he left her.
Portuguese police officer Paulo Ferreira told the court Mrs Yates, who was born in Merseyside, had so many injuries it was difficult to tell which one had killed her.
Prosecutors had said in their pre-trial indictment that Mrs Yates had bled to death from her neck wounds.

Police also revealed that a small oven in the bathroom of her bedroom suite appeared to indicate she took refuge in confined areas of the house for long periods of time.
