Tamil Nadu chief minister J Jayalalithaa walked out of the NDC meet when she was interrupted during her speech. "I was humiliated at the NDC meet. No chief minister can be expected to wind up her speech in 10 minutes. If the government has called me all the way to New Delhi to deliver a 10-minute speech, it is unacceptable," she said speaking to CNN IBN from her car.  "This is the centre's way of stifling a opposition state's voice," she added for good measure.
