Sacked Rajasthan minister Rajendra Gudha called for a narco test on all ministers in the state on Tuesday, a day after he waved a 'red diary' in the assembly alleging it contained details of financial irregularities involving Chief Minister Ashok Gehlot and others. In an interview with PTI, Gudha also took sides with senior Congress leader Sachin Pilot in the now-off, now-on tussle between Gehlot and his former deputy.
