Ehud Olmert, who was Israeli prime minister between 2006 and 2009, has spoken about who he thought was to blame for the security failings ahead of the Hamas attack on Israel on 7 October.
Hamas has been proscribed as a terrorist organisation by the UK and other governments.
During his time in office, Mr Olmert wanted a two-state solution, offering to withdraw from most of the occupied West Bank.
His deal ended when he was forced from office in a corruption scandal.
BBC Newsnight’s Joe Inwood spoke to him about the Israel-Gaza conflict.
