The forthcoming panchayat elections in West Bengal are shaping up as a test for the BJP, which is seeking to retain its position as the main opposition in the state as the CPI (M) and Congress revive to be its challengers. State BJP leaders said even though the saffron party is much better placed to take on the ruling Trinamool Congress in terms of organisation than it was five years ago, the revival of the Congress-CPI (M) alliance has led to a dip in the right-wing party’s share in the opposition vote, which was pocketed entirely by it till the 2021 assembly polls.
