Labor's national executive has seized control of the Victorian branch for up to three years, placed it under the control of administrators and will audit every member, as it moves to clean out the division in the wake of allegations of widespread branch stacking.

The national executive ratified the move on Tuesday night. Party stalwarts Steve Bracks, a former Victorian premier, and Jenny Macklin, a former federal minister from Victoria, will be appointed to administer the branch until at least the end of January. All officials and staff will be required to report to them.
