Bangalore, Jan 09 (ANI): Karnataka Janta Party (KJP) president B S Yeddyurappa and two of his party MLAs formally rejoined the Bharatiya Janata Party (BJP) on Thursday. Speaking on the occasion, Yeddyurappa said that the decision to quit the BJP was wrong in hindsight, as it had helped the Congress to come back to power. He said the need of the hour for the BJP was to stay united and to aim for 20 Lok Sabha seats from Karnataka.
