Federal Liberal Party President Nick Greiner concedes Tony Abbott shares some of the blame for the leadership crisis that saw Malcolm Turnbull stripped as leader of the parliamentary Liberal Party this week. Mr Greiner says the former prime minister should have been more focused on bringing down the political opposition in Labor, than focusing on internal differences. However, the party president stopped short of saying Mr Abbott should quit parliament, insisting that it is a decision for each individual MP. Image: Kym Smith / News Corp Australia
