"The Joint Parliamentary Committee probe into alleged irregularities in the 2G spectrum will serve to humiliate Prime Minister Dr Manmohan Singh and he may resign which is what Sonia Gandhi wants," Swamy said.
"The opposition should take care that they don't play Sonia Gandhi's game," he told PTI after meeting Shiv Sena supremo Bal Thackeray at the latter's residence Matoshree in Mumbai.
Asked if he thought Sonia Gandhi was instigating opposition to insist on the JPC probe, Swamy said, "Yes, I think she is instigating the opposition for a confrontation on this issue so that the prime minister loses."
On whether the opposition was playing into her hands, Swamy said, "I think if the PM were forced to resign at this juncture, you are empowering Sonia Gandhi so that she is free to bring in Rahul Gandhi as the prime minister."
"I have urged Balasaheb to organise a rally against corruption and he has agreed for it. It will be held at the Shivaji Park," he said.
"I requested Balasaheb to lead the country and get rid of the rampant corruption," he added.
