Kerala Chief Minister Pinarayi Vijayan has reason to feel major end-of-year blues. The CBI is ready to move the Supreme Court to challenge his acquittal in a corruption case dating back to the 90s, NDTV has learnt. Just days ago, he was forced to nudge a minister to resign after he was indicted for illegally appropriating land - it was the third exit from his cabinet in Mr Vijayan's one and a half years in power.
