Queensland opposition leader Deb Frecklington and two of her frontbenchers have apologised for accusing Deputy Premier Jackie Trad of ignoring corruption allegations against Ipswich City Council.
Ms Frecklington, her deputy, Tim Mander, and education spokesman Jarrod Bleijie on Tuesday accused Ms Trad of ignoring 326 complaints when she was local government minister between 2015 and 2017.
Their claim was based on a Right to Information request relating to complaints received by Ms Trad about the scandal-plagued council.
Ms Trad said the figure referred to the number of pages in a document relating to just three accusations, which were referred to the Crime and Corruption Commission.
The three MPs apologised minutes before parliament adjourned on Thursday night.
Ms Trad will write to Speaker Curtis Pitt asking him to refer the Liberal National MPs to the ethics committee for misleading parliament.
"This notice clearly stated that there were 326 pages of material located as being within scope," she said under parliamentary privilege on Wednesday.
"It did not state there were 326 complaints, as was claimed."
