Italian mafia boss Bernardo Provenzano has died in jail, aged 83.

Provenzano, dubbed “The Tractor” for his ruthless trait of mowing people down, was arrested and jailed in 2006 after spending 43 years on the run.

He was said to have taken over command of the Sicilian Mafia after the 1993 arrest of ex-boss Salvatore “Toto” Riina.

Provenzano was serving a life term for several murders, including the killing of two judges in 1992.

He was suffering from bladder cancer and serious cognitive impairment and had spent the last two years in a hospital ward, Italian media report.

His illnesses had forced the suspension of ongoing negotiations with the state over unresolved crimes.
