Senator HANSON-YOUNG (South Australia) (14:19): Both the government and the opposition have indicated they'll support the TPP, but Senator Cameron, in leaked caucus minutes, said, 'It's bad economics and bad politics.' Minister, could you answer my original question: can you withdraw; can you renegotiate? How on earth is the Labor Party going to deliver on this promise? The PRESIDENT: I'm calling on Senator Birmingham to answer that part of the question that was within his ministerial responsibilities.
