Terror suspect Daniel Khalife's escape from HMP Wandsworth – believed to be by strapping himself underneath a delivery lorry - led to a police manhunt involving all 43 forces in England and Wales. The 21-year-old ex-soldier was on remand charged with collecting information which might be useful to an enemy, understood to be Iran. The justice secretary, Alex Chalk, has told MPs that an independent investigation will take place, while suggestions have been made that cuts to the Prison Service and overcrowded conditions at Wandsworth prison are partly to blame. But what does his escape tell us about the state of the prison system in England? On the Sky News Daily, host Niall Paterson speaks to David Shipley, a former inmate at HMP Wandsworth, and Professor John Podmore, an ex-prison governor and inspector, about what's wrong with Wandsworth prison and others across the country?
