A day after touting London as inspiration for the privatisation of Adelaide's passenger rail operations, South Australian Transport Minister Stephan Knoll blunders on-air by appearing to be unaware the Tube was back in public hands.
The London Underground train network was transitioned into a Public Private Partnership (PPP) by the Labour Government in 2003 but one of the private contractors, Metronet, went into administration in 2007.
According to a 2012 House of Commons briefing paper, the PPP was "plagued by problems" and "collapsed" when Government body Transport for London bought out Tube Lines consortia in 2010.
