Julia Gillard has moved to support Labor's marginal seats by throwing out the contentious resources tax so that the political controversy can be nipped.

Meanwhile, there are speculations that the peace pact in Canberra yesterday will not help Opposition Leader Tony Abbott, while he works for removal of the tax in case the Coalition comes up with flying colors in the elections.

Mr. Abbott recently announced that the political tiff between him and Ms. Gillard would be ''referendum on tax''. On the contrary, the Prime Minister put forth her concession with Australia's largest mining Companies, which are expected to witness a 30% tax over their potential profits.

Highlighting its win following the demanding week of backroom discussions with Treasurer Wayne Swan and Resources Minister Martin Ferguson, the resources sector told that the real tax rate is 22.5%.

Also, the Government accepted that it will be applying the new tax on the iron ore and coal industries only and the current petroleum resources rent tax will be covering oil and gas plus projects on the North-West Shelf.

The tax has been renamed from confrontational ''super profits'' to a more impartial “the Minerals Resource Rent Tax or MRRT.

All the major miners and Minerals Council of Australia seemed satisfied with the deal.
