Ahmadinejad raised the proposal at a press conference two days before a U.N. Security Council deadline demanding Tehran suspend uranium enrichment.

He told the reporters that "I suggest holding a live TV debate with Mr. George W. Bush to talk about world affairs and the ways to solve those issues."

The Iranian president, meanwhile, complained about the U.S. and British role in the world affairs, saying "the U.S. and Britain are the source of many tensions."

"At the (UN) Security Council, where they have to protect security, they enjoy the veto right. If anybody confronts them, there is no place to take to complaints," said Ahmadinejad.

However, Ahmadinejad expressed that Tehran still expects a positive outcome of its response to a six-nation nuclear package.

But he warned that Iran will react in its proper ways if the UN Security Council imposes sanctions on it, saying "we have said everything in our response. I think the time to use the instrument of the Security Council has expired."

"I see it as unlikely that they want to use it (the Security Council). Using nuclear energy is Iran's right and we want to use it according to international law," said the president.

The Security Council adopted the resolution late July, urging Tehran to suspend by Aug. 31 all enrichment-related and reprocessing activities, including research and development, or face prospect of sanctions.

Iran has rejected the resolution as having no legal basis.
