Controversial MP Craig Kelly has ruled out joining any other party after resigning from the Liberals.

The controversial MP is promising to vote with the government on matters of supply and confidence while he sits on the crossbench.

“I believe I’m best to speak independently so I can speak my mind, fearlessly and freely.”
