SUNSHINE Coast MP Peter Slipper is urging voters to put Mal Brough last on September 7, saying he will not be an effective member for the people of Fisher.
Mr Slipper said in a statement on Monday night that while he was yet to decide on where he would be directing other preferences, he had decided who would receive his last preference.
"In arriving at this decision I have considered carefully the suitability of the various candidates for election to the Federal Parliament".
"I have decided to place Mal Brough at the bottom of my how to vote card".
"I have known Mr Brough for many years and have not been impressed with what I observed.
"When Member for Longman he suffered the biggest swing of any Liberal Member at the 2007 poll and in the view of many people was not an effective local member".
"Mr Brough sought to strut the national stage and many of his constituents complained to me they couldn't get an appointment with him.
"Added to this he branch stacked in Fisher by signing up large numbers of people as members to vote for him at a pre-selection and effectively forced me out of the LNP after decades of membership.
"Also adverse findings against Mr Brough have been made by Justice Rares in the Federal Court when he threw out the Ashby case, in which Mr Brough was deeply involved, as an "abuse of process".
"I note Mr Brough unlike some others adversely mentioned by the Judge did not seek leave to appeal the adverse findings against him by the court."
Mr Brough has rejected the findings of the court, denying he was involved in any conspiracy with James Ashby to bring sexual harassment allegations against Mr Slipper.
Mr Slipper has not denied he sent lewd text messages of a sexual nature to Mr Ashby but last week claimed they were between friends and not an employer and employee.
The former Speaker is also facing charges for alleged Cabcharge fraud following extensive investigations into his huge travel expenses by the Sunshine Coast Daily over the past few years.
Mr Brough, who has a campaign office in the same building at Kawana as Mr Slipper's electorate office, has told media it has been Mr Slipper who has been absent on the job.
Mr Brough said he had fielded inquiries from constituents who had not been able to get an appointment with Mr Slipper.
Mr Slipper denied this on an ABC interview last week.
