The Greens national leader Senator Bob Brown says that Labor advertisements attacking opponents in Tasmania and South Australia undermine decency in Australian public life.
Referring to Labor's pre-election ads attacking the Liberals in South Australia and Greens in Tasmania with false claims of affinity for crimiansl or drugs, Senator Brown called on Prime Minister Rudd to intervene.
"This gutter stuff from Labor in both states requires decent leadership to intervene and call it what it is - unacceptable.
"It demeans every voters right to be fairly informed.
"Politics can be rough and tumble but Labor's new tactic low brings the worst of fringe group extremism centre stage.
"Mr Rudd should tell his state counterparts to lift their game," Senator Brown said.
