Jackie Trad in the clear over house buy

Queensland Deputy Premier Jackie Trad has been stripped of responsibility for the state's biggest infrastructure project, the $5.4 billion Cross River Rail, despite being cleared of corruption by the state's Crime and Corruption Commission.

After months of damaging claims over integrity issues, the Palaszczuk government received a circuit-breaker on Friday when the CCC announced it would not launch a formal investigation over Ms Trad's purchase of an investment property, which she did not promptly declare to Parliament.
