Assam finance minister and BJP's key strategist for the northeast, Himanta Biswa Sarma said on Sunday that the state has taken the visit by the delegation led by Trinamool Congress lawmaker Derek O' Brien positively, since "any political party has the right to visit terror attack victims." The cautious move by the BJP leader comes in the backdrop of the 2019 elections, when the Bengali Hindu votes are important for the party in both Assam and West Bengal.
