Congress leaders on Wednesday accused the Bharatiya Janata Party (BJP) of attempting to weaken Opposition parties to secure the numbers required to pass key Bills in Parliament, amid speculation over "Operation Tiger" and reports of efforts to lure Shiv Sena (Uddhav Balasaheb Thackeray) lawmakers into the Eknath Shinde-led Shiv Sena.

The remarks came against the backdrop of political buzz surrounding possible defections from the Uddhav Thackeray-led Shiv Sena (UBT) camp.
