A ruling Shiv Sena leader has predicted a "major political earthquake" in Maharashtra on January 23, the birth anniversary of Shiv Sena founder late Bal Thackeray, claiming that 10 to 15 MLAs from the opposition Congress and the Shiv Sena (UBT) will switch sides and join the party led by Deputy Chief Minister Eknath Shinde. The prediction comes amidst reports of discontent within the ruling coalition in the state.
