Mr Speaker, my question is to the Prime Minister. I refer the Prime Minister to the Treasurer's claim that the carbon tax will have 'a modest impact on prices'. Can the Prime Minister confirm that this increase will add to the cost of electricity, gas and water bills, which have risen 43.9 per cent since Labor came to power, and the price of fruit and vegetables, which have risen 35.4 per cent. I ask the Prime Minister: is this really the right time to introduce a trillion-dollar carbon tax that will increase the cost of everything?
