All Jharkhand Students' Union-chief Sudesh Mahto, who had snapped ties with the ruling BJP ahead of the Jharkhand state-polls, is leading by nearly 20,000-votes in Silli, his former stronghold where he lost in 2014 after retaining the seat for 15-years. The 45-year-old, one of the most prominent candidates in the state-election, is ahead of the incumbent MLA and Jharkhand Mukti Morcha leader Seema Devi.
