Muhammad Ali is fighting for his life, says his brother, Rahman Ali, in an interview with the UK's Sun newspaper.
The former heavyweight champion, 71, is gripped by Parkinson's and Rahman Ali fears he is in terminal decline.
But the 69-year-old said the disease is NOT the most devastating factor in Ali's heartbreaking demise.
He blames Lonnie, his wife of 26 years, for tearing the family apart and said Ali would be "mad as hell" if he knew what was going on.
He said: "The worst thing to happen is not the illness, but his wife."
In an exclusive interview, Rahman broke down in tears as he admitted he would rather his brother died now so he can escape his suffering.
