Mumbai: Shiv Sena leader Uddhav Thackeray on Saturday cautioned ally BJP against virtually dumping a senior leader like L.K. Advani.

"There is talk that a 'Modi era' has started in BJP, but the 'Advani era' has not yet ended in the country's politics. He has achieved this pinnacle of success by his struggles and sacrifices in public life," Thackeray said in an editorial in party mouthpiece 'Saamana'.
