When asked whether Congress should have given more thought before assigning minister portfolios, he said, "Portfolios were sold. How can I blame Kumaraswamy for it? He wasn't allowed to function. From day one Siddaramaiah said he is going to be the chief minister. You have gone to their doorstep to form the government." Responding to this, Gundu Rao said: "It is unbecoming of a politician of his stature to be speaking like this, it reeks of pure political opportunism. We will take the required action when the time is right." Arshad called Baig an "opportunist" and asked him to resign from the party. "He is an opportunist. If he has guts let him resign and contest from the BJP. If Congress is such a bad party which gave him power for the last 10 years and made him MLA for the last four terms let him resign and contest from BJP. Let's see what happens in Shivajinagara," he said. Click here for Live updates also read: BJP candidate Giriraj Singh leads, Kanhaiya Kumar trails
