The bedroom tax has been "mismanaged from the start" and has failed to free up larger properties, according to Labour.
Shadow welfare minister Chris Bryant said:
This ill-conceived policy has been mismanaged from the start.
It's failed to free up larger properties because there simply aren't smaller properties to move to.
It's hitting the most vulnerable hardest, and failing to save the money that David Cameron had predicted.
The Government has no reason to keep it - if they won't repeal it, a Labour government will.
