LABOR has hit back at claims its advertising targeting Denison independent MHR Andrew Wilkie is defamatory.
The advertisements say "If Andrew Wilkie wins Dension, Tony Abbott is one seat closer to becoming prime minister," and "Vote Wilkie - Get Abbott" and have been in use since July1.
Mr Wilkie said the advertisements suggested he had made a deal to support the Liberal Party.
"That's blatantly misleading and defamatory because I have made it very clear that I will not do any deal with any party after the election to help them form government," Mr Wilkie said.
"So that every time the Tasmanian ALP say that a vote for Wilkie is a vote for Abbott, they are effectively calling me a liar."
Mr Wilkie said he would also not make a preference deal with any party or candidate.
He wrote to Prime Minister Kevin Rudd about the issue billboards yesterday.
Australian Labor Party national secretary and campaign director George Wright responded to the letter yesterday afternoon, and said the ads were a matter of "simple arithmetic".
"There is nothing defamatory or misleading in the ALP advertising you complain about," the letter says.
"You have ruled out supporting a Labor government.
"If [Labor Denison candidate] Jane Austin is elected, this is one more MP supporting a Labor government."
