MOORS murderer Ian Brady was reprimanded by the judge hearing his mental health tribunal after first walking out then complaining he had listened to the proceedings "ad nauseam."

The 75-year-old child killer, who is demanding to be moved from a maximum security hospital to end his days in a Scottish prison, spoke out after claiming a panel member had fallen asleep at one point.

But Gorbals-born Brady, who killed five young people with his partner in crime Myra Hindley, told the tribunal a criminalologist's evidence yesterday about his mental state had been well rehearsed previously. "I've listened to this ad nauseam. I know it by heart," Brady said in his distinctive Scots accent.

However, Judge Robert Atherton warned him his tribunal would hear the evidence, adding: "If we take the view someone is wasting time you can be pretty certain they will be told."

It came after the expert, Dr Adrian Grounds, told the first day of the hearing on Monday that Brady was feigning mental illness.

Brady, who had not been seen or heard in public since his trial in 1966 before the start of the tribunal, is being forced fed at Ashworth Hospital near Liverpool. He wants to be judged sane so he can be moved north of the Border, claiming he will be free to starve himself to death in prison there.

Brady could barely be heard as he was asked by the judge if he wanted to say anything about Dr Grounds's evidence. Referring to panellist Dr Cameron Boyd, Brady said: "It even apparently lulls him to sleep."

Brady was described as contemptuous of his peers. He shows anger that can erupt over minor matters and unleashes verbal tirades against staff and other patients, the tribunal heard.

Brady, who has been on hunger strike since 1999, claims he has faked psychotic episodes by "acting" in the past. Hospital records from January 29 this year stating how Brady has now almost totally isolated himself, the hearing was told.

Following a seizure last July, hospital notes recorded him saying: "If I have to, I will never let them see me in pain. I will act as if I have not a care in the world."

Brady is currently "nursed" in the hospital setting because he is regarded as being severely mentally ill. But if he was deemed fit to be returned to a jail, the regime would be much less "tolerant and flexible" of his behaviour and the abuse he metes out to staff and others, the tribunal heard.

Dr Grounds was called by Brady's legal team to support his case. He said Brady wished to have control over the manner and timing of his death but that view did not arise out of mental illness. Brady reasoned he had no prospects of release or of a better life.

He said Brady's lifelong severe personality disorder had not diminished, but psychotic symptoms of mental illness shown in prison had reduced. He added that he could relapse if transferred to prison but added the penal system could manage his current condition.

The hearing, which is due to last up to two weeks, is due to continue today.
