Former Chief Supt David Duckenfield faces a manslaughter charge and five others will be prosecuted over the 1989 Hillsborough disaster.
Mr Duckenfield was the South Yorkshire Police (SYP) match commander at the FA Cup semi-final when 96 Liverpool fans were fatally injured in a crush.
He faces the charge of manslaughter by gross negligence of 95 fans.
Former SYP Ch Insp Norman Bettison will be charged over alleged lies in the aftermath.
Victims’ relatives have been informed.
Last year, new inquests into the disaster at the Liverpool v Nottingham Forest match in Sheffield concluded the fans had been unlawfully killed.
For legal reasons, Mr Duckenfield cannot be charged over the death of the 96th victim Tony Bland, as he died fours years after the disaster, prosecutors said.
The Crown Prosecution Service (CPS) must apply to the High Court to lift an order imposed after he was prosecuted privately in 1999, which must be removed before he can be charged.
