Union home minister Amit Shah will be in Bengal on a two-day tour on December 19 and 20, the party announced a day after its national president J.P. Nadda’s convoy had allegedly been attacked on its way to Diamond Harbour on Thursday. Multiple BJP leaders said Shah would up the ante against the Trinamul Congress on the alleged attack and lay stress on the “breakdown” of law and order in the state, which would be a major plank of the campaign for the party in the 2021 Assembly polls. “Amit ji will be in Bengal on a two-day tour... He will visit North 24-Parganas and Birbhum,” said BJP state general secretary Sayantan Basu.
