Doctor Conrad Murray has insisted he and the Michael Jackson were like ''family'', and has claimed he didn't kill the star, despite being charged with involuntary manslaughter over the singer's death in 2009.

The disgraced former doctor - the 'Thriller' hitmaker's private physician who was charged with involuntary manslaughter when the singer died in 2009 - has claimed he and the late star were like ''brothers''.

He told the Mail on Sunday newspaper that Michael had held his hand and said: ''There are only four people in my family now. Paris, Prince, Blanket and you, Dr Conrad.''

Conrad added: ''[It was] one of the happiest days of my life. This man who had been so lonely, who had spent so many long nights telling me about his pain and anguish, finally felt he could trust someone in his life apart from his children.

''We were family. We loved each other as brothers.''

He has also insisted he did not kill the iconic singer, instead claiming he overdosed himself on propofol as he was suffering from insomnia, which Conrad claims could have been because of withdrawals from demoral, which he was apparently given by another doctor.

He said: ''I never gave Michael anything that would kill him. I loved him. I still do. I always will ... That night he just couldn't sleep.

''I prescribed him drugs to help, including valium and lorazepam, but he was begging, pleading ... I told him, 'This is not normal. What I've given you would put an elephant to sleep'.

''In the other bedroom [Michael's private chamber], the police found an open bottle of lorazepam. They found tablets in his stomach. I didn't give him those. Michael took extra tablets. And he injected himself.''
