After former Karnataka deputy chief minister Laxman Savadi decided to join the Congress on Friday, BJP Karnataka in-charge Arun Singh said that the former has made a big mistake and will regret it later. While talking to ANI, Singh said, "Even after losing the election, BJP made him deputy CM and then MLC, even after that, he is going to a party (Congress) with such quarrels where the leaders are divided into two groups. He has made a big mistake and will regret it later."
