Union Home Minister Amit Shah was in West Bengal in the past two days. The senior BJP leader used the opportunity to promise that the Citizenship Amendment Act will be implemented in West Bengal without fail.

At a time when there are rumours that the Centre has no political will to see through the CAA (and also the contentious National Register of Citizens), Shah played the card less than a year ahead of the Assembly elections in Bengal.

Shah surprised everyone by focusing on Bengal instead of Bihar, where the final phase of polling is being held on Saturday. "It shows that BJP is super-confident of NDA's victory in Bihar. On the other hand, it wants to up the game in the Mamata Banerjee land early on," a commentator said.

CAA and NRC are expected to become major poll issues of BJP in the run-up to the Assembly elections in Bengal. Recently, Narendra Modi said that the Opposition had peddled the lie that the CAA will rob many Indians of citizenship and that none has lost citizenship because of the contentious law.
