The new BJP government is scheduled to face a vote of confidence in the legislative assembly on July 29 for which a session is being convened.
BS Yediyurappa had taken charge as Chief Minister on Friday, hours after he was sworn in by Governor Vajubhai Vala.
Mr Yediyurappa staked claim to form the government, three days after the 14-month old Congress-JD(S) coalition government fell after losing the trust vote in the Assembly.
