Queensland Premier Campbell Newman has stood by claims Clive Palmer tried to buy his government, saying the public deserved to know how the businessman-turned-politician operates.
Mr Newman's lawyers on Wednesday lodged a defence against a statement of claim for defamation the Palmer United Party leader made against him last month, seeking $1.1 million in damages.
Mr Palmer alleges the premier has damaged his reputation by describing him in a press conference in April as "a guy who tried to buy ... my government".
But in the defence claim, Mr Newman's lawyers say the comment was in the public interest.
"The public had an interest in receiving information that might lead them to ask (how Mr Palmer) ... in his capacity as a businessman sought to influence government decision making in relation to his business interests," the defence documents read.

It goes on to detail a meeting with Deputy Premier Jeff Seeney in 2012 where Mr Palmer wanted him to allow the development of "Port Palmer" at Abbot Point and give him exclusive access to a rail corridor to the Galilee Basin.
"(He said) he had paid substantial sums to the LNP to have the LNP elected and that he had a lot more money to support the LNP in the future," it read, adding Mr Seeney refused the offer.
Mr Newman's lawyers also claimed former Liberal National Party MPs Carl Judge and Alex Douglas received "substantial gifts" from Mr Palmer and his companies to switch allegiances.
The premier said Mr Palmer didn't complain to the police or Crime and Misconduct Commission about his comments or even seek an apology.
Mr Palmer has denied claims he offered donations to the LNP for favourable treatment.
"Campbell Newman is simply telling untruths or he has been told lies by Deputy Premier Jeff Seeney and is using them to try and defend the defamation action," Mr Palmer said in a statement on Thursday.
"This is nothing more than a desperate attempt by desperate people to discredit me."
Mr Newman said his last donation to the LNP was in 2010 - two years before the Newman government was elected.
