Chidambaram never won election, must quit: Jayalalithaa

"He has not won the parliamentary election. In fact he lost the election," the AIADMK leader told a news conference here. "He has played a fraud on the nation."

Jayalalithaa said the data entry operator in the Sivaganga Lok Sabha constituency in Tamil Nadu transferred votes secured by AIADMK candidate Raja Kannappan to Chidambaram's credit in the 2009 general elections.

"This is how this fraudulent victory was secured," he said. "He should resign."

The chief minister said her party candidate had filed a case in the Supreme Court challenging Chidambaram's victory. "There is no question of softening our stand. We will try to expedite the case."

She said Chidambaram's position in the cabinet was "untenable". According to official records, Chidambaram defeated his AIADMK opponent by 3,354 votes.
