TONY ABBOTT says he will call a double dissolution election if he wins power and Labor and the Greens combine in the Senate to stop him from repealing the carbon tax.

The Opposition Leader, who is sitting on a massive election-winning lead in the polls, issued the edict in front of a community forum in Brisbane last night.

He said if the government was ''walloped'' at the next election over the carbon tax, it would be unthinkable that a humiliated Labor would not allow an Abbott government to rescind it.

Mr Abbott said he would have a mandate to rescind the tax which would be equal to that of Labor when it repealed Work Choices after its 2007 victory.
