Suthep was reacting to Thaksin's Twitter message about leading the red shirts to force the government exit. The red shirts are scheduled to hold a rally from November 29 to December 3, billed as a showdown.
"I deem it inappropriate for Thaksin to fight with unconventional means; everything should be in accordance with the political system," he said.
Commenting on Thaksin's claim to have intervened and arranged for the release of a Thai man charged for spying in Cambodia, he said he did know the details.
"If anyone can help saving a Thai, then the government is not losing face because a man's life is more precious than a political game," he said.
