Senior BJP leader L K Advani's former aide Sudheendra Kulkarni on Tuesday appeared before a Delhi court in response to its summons for his alleged role in the 2008 cash-for-vote scam. Kulkarni appeared before Special Judge Sangita Dhingra Sehgal after repeatedly failing to do so on the 6 and 19th of this month on the ground that he was in the US. The court had on the 19th warned his counsel that his failure to appear on the next date would force it to issue arrest warrant against him.
