Sticking to her stand for a Joint Parliament Committee (JPC) probe into the 2G spectrum scam, AIADMK chief Jayalalithaa on Sunday said it is a "mystery" why no follow up action had been taken after A Raja resigned as Telecom Minister.
"That is sad. It is a mystery why the central government has not thought it fit to order a probe (against Raja) and why there is no interrogation or arrest," she said in response to a question from reporters here.
Jayalalithaa said there was no change in the opposition stand for a JPC probe. "There is no change. AIADMK will stick to its stand a of JPC."
On Tamil Nadu Chief Minister M Karunanidhi playing the Dalit card in defence of Raja, she said "It is meaningless to drag his caste into an act of corruption".
