Curtis Pitt, the long-standing Speaker of Queensland Parliament and Mulgrave MP, has announced he will quit politics at the upcoming state election.
In a statement on social media, the 46-year-old said he didn't come to the decision lightly but wanted to be there for his family.
"I've always said that the day I wake up and don't feel I can give it 100 percent, then it's time for me to do something else," he said.
"When I think back, all of my kids have been born since I've been an MP.
"Having been a member of Parliament for five terms, I know that I've missed so many important milestones and occasions. I want the chance to be there for my children during an important phase of their life.
"I also have parents who have failing health and just like they've been there for me, I want to be there for them."
Pitt has been MP for more than 15 years and served as Speaker for six years.
In his long political career, he has worked as Queensland Treasurer, acting Premier and served as a minister on a number of portfolios.
He will continue as MP until the election in October, when he will step down, and will remain as Speaker until a new presiding officer is elected.
"For the first time in a long time, I don't know exactly what's next for me," he said.
"But I know that I've given all I can to this job and the people I've been so honoured to represent in my local area.
"It's now the time to give all I can for the people closest to me - my family and loved ones."
