Legendary boxer Muhammad Ali is so ill he could be dead within days, his brother has warned. 

Rahman Ali said the former heavyweight champion cannot speak and no longer recognises him. 

Rahman fears his 71-year-old brother - known as The Greatest - may not survive the summer. 

He told The Sun: 'He's in a bad way. He's very sick. 

'It could be months, it could be days. I don't know if he'll last the summer. He's in God's hands.'

Ali was diagnosed with Parkinson's disease in 1984 but remained active for many years and made a moving appearance at the Atlanta 1996 Olympic Games where he lit the flame. 

However, he was seen looking particularly thin and frail at the London 2012 Olympic opening ceremony where he was helped across the stage by wife Lonnie. 

Rahman has accused his sister-in-law, who has been married to Ali for 26 years, of refusing to let the family visit the ailing champion.
