A day before voting for the first phase of the Lok Sabha polls, Prime Minister Narendra Modi and his BJP have received a major jolt from the Supreme Court. The apex court, on Wednesday, decided that leaked confidential documents suggesting the PMO’s interference in negotiations on the Rafale deal, can be relied upon while adjudicating on a bunch of petitions that have sought a review of the court’s verdict of December 14 last year which had rejected prayers for an investigation into the fighter jet deal.
