The Nationals do not support Mr Iemma's highly controversial proposal to privatise the State's electricity assets in its current form.

"He has not provided sufficient details and has a track record of failing taxpayers when he negotiates with the private sector," Nationals Leader Andrew Stoner said.

The Coalition has put forward a set of safeguards that Mr Stoner says will get the best outcome for taxpayers.

"All week the Premier has refused to detail for the public his plans on power privatisation," Mr Stoner said.

"Morris Iemma's main objective this week has been to meet the demands of the union movement."

According to Mr Stoner, Mr Iemma is now faced with a stark choice.

"He either meets our demands or we will oppose him at every corner," he said.

"At the heart of our calls are guarantees on prices, service levels and jobs, and making sure country towns and cities are protected."
