The former director of Altcourse prison told an inquest that he believed he did "all he could reasonably do" to make it safer despite rocketing levels of violence on his watch.
Bob McCombe, who took over at the private G4S run jail in May 2013, was grilled over what strategies senior managers implemented in the months before inmate Darren Ashcroft was stabbed to death on November 14, 2014.
Mr Ashcroft, 35, died after being attacked by 41-year-old Keir Michael on the Fazakerley prison's troubled Valentines Green wing - where police investigating his death later found 22 makeshift weapons including knives and razor blades.
