Home Minister Amit Shah on Wednesday said political parties with diametrically opposite ideologies have come together only to grab power and have discredited the mandate given by the people of Maharashtra. Speaking at a summit organised by Republic channel, the minister said people voted for a stable government in Maharashtra with a pre-poll alliance between his BJP and the Shiv Sena winning people's mandate. He said moral and ethics have been distorted just to keep the BJP out of power. "Is it not horse-trading to take support by offering the chief minister's position. I am again telling Sonia Gandhi and Sharad Pawar to claim chief minister's post and then take Shiv Sena's support," Shah said.
