Former Prime Minister Manmohan Singh is likely to seek a stay order on summons and ask the high court to discharge him as an accused. Manmohan Singh has been summoned as an accused along with five others in a case linked to the coal scam that saw mining rights being assigned without any transparency to private firms. A special CBI court has also named Hindalco, its chairman Kumar Mangalam Birla, and former coal secretary PC Parakh among the six accused.
