KEPPEL MP Brittany Lauga has backed Annastacia Palaszczuk's handling of Billy Gordon, the Member for Cook who was ousted from the Labor Party this week.
Ms Lauga said Ms Palaszczuk had done the right thing by removing him from the party and referring matters to the police after details of an unreported past criminal history were revealed.

Ms Lauga said the Member for Cook had the opportunity to disclose his history prior to the election.
"It should have been disclosed during pre-selection. There are questions related to criminal history... that was the opportunity he had to disclose," she said.
"She (Palaszczuk) has done the right thing. The Premier dealt with it swiftly, handled it rationally, methodically and fairly... she wanted a government full of integrity and accountability.
"She is sending a message to Queensland that she truly believes in."
Ms Lauga said the situation was disappointing to fellow Labor MPs and the community.
"Everyone in Caucus is bitterly disappointed," she said.
"We work together, rely on each other, depend on each other… this has let us down, it's very disappointing.
"The indigenous community was celebrating his election, it's unfortunate it had to end this way."
Ms Palaszczuk announced the dismissal on Sunday.
"I'm appalled and I'm shocked and I feel sick to the stomach," she said.
The removal of Mr Gordon from the Labor Party has cast uncertainty on the government's future.
