Former NSW Labor premier Kristina Keneally has made a formal complaint to her Sky News bosses after an on-air attack on her from fellow presenter Mark Latham.
On Tuesday night former federal Labor leader Latham launched into Keneally on Jones & Co, describing her as a "Yankee sheila" and a "protege of Eddie Obeid", the disgraced former Labor powerbroker.
There were a number of other comments about her political career which Keneally is believed to consider defamatory.
There have been a number of skirmishes between presenters in recent weeks, following Ross Cameron's controversial comments at a right-wing fundraising dinner.
