Tax cuts for big businesses will be put to a vote in the Senate this fortnight, but Finance Minister Mathias Cormann is refusing to say whether the policy will be abandoned if the bill fails.
The Federal Government wants to slash the tax rate for businesses turning over more than $50 million per year from 30 to 25 per cent.
But it faces stiff opposition from the Senate and some members of the Coalition.
Coalition frontbencher Christopher Pyne has told the A-B-C claims of division in party ranks over the company-tax cut plan are exaggerated.
Former prime minister Tony Abbott has warned Australia will be surrendering its sovereignty if his coalition colleagues support the National Energy Guarantee.
Mr Abbott says he's concerned the Turnbull government's signature energy policy would lock in a binding carbon emissions reduction target.
He's told Radio 2GB.. the Paris Agreement agreed to targets on a non-binding and non-mandatory basis.
