BJP–Shiv Sena Rift Deepens Over BMC Mayor Post as Bal Thackeray Legacy Looms Large

Fresh fault lines have surfaced within Maharashtra’s ruling Mahayuti alliance as negotiations over the Brihanmumbai Municipal Corporation (BMC) mayor’s post hit a stalemate, exposing deeper tensions between the Bharatiya Janata Party and the Shiv Sena led by Eknath Shinde. The dispute has gained political and emotional weight as 2026 marks the birth centenary of Shiv Sena founder Bal Thackeray.

The immediate flashpoint is the Shinde-led Sena’s demand that the BMC mayor’s post be shared on a rotational basis, with the party seeking to hold the position for the first two-and-a-half years of the five-year civic term. While the BJP has emerged as the single largest party in the 227-member BMC with 89 seats, Shinde’s Sena secured 29 seats, giving the Mahayuti alliance a slim majority of 118, just above the required 114.

Despite the numerical advantage, the alliance has been unable to finalise leadership for Asia’s richest civic body weeks after the election results. The friction became public when the Shinde-led Sena abruptly cancelled the registration of its corporators for BMC proceedings, leaving party members waiting at the headquarters without explanation. The move was widely seen as a signal of dissatisfaction with the ongoing power-sharing talks.

The dispute is not merely administrative. For Shinde, securing the BMC mayor’s post during Bal Thackeray’s birth centenary year carries symbolic significance. Under the undivided Shiv Sena, the party dominated Mumbai’s civic body for nearly three decades. During the late 1990s, the Sena simultaneously held the Chief Minister’s post and the BMC mayor’s chair — an arrangement deeply associated with Bal Thackeray’s political vision.

Both the Shinde-led Sena and the opposition Shiv Sena (UBT), led by Uddhav Thackeray, now claim to be the true inheritors of that legacy. Leaders from the UBT camp have used the centenary year to urge Shinde to break ranks with the BJP and reunite the Shiv Sena, framing it as the ultimate tribute to the party founder.

Tensions have also played out within the Mahayuti government. Shinde skipped a key Cabinet meeting and a scheduled discussion with Chief Minister Devendra Fadnavis, instead travelling to his native village in Satara district. Several ministers from his faction also stayed away from a meeting chaired by Fadnavis, fuelling speculation of a deeper rift.

Behind the scenes, the BJP is reportedly willing to concede control of the Thane Municipal Corporation to the Shinde Sena, while seeking dominance in the BMC through the mayor’s post and the powerful standing committee. In other civic bodies such as Kalyan-Dombivli and Ulhasnagar, where both allies enjoy similar strength, negotiations are centred on equal power-sharing.

Leaders from both sides have publicly downplayed the discord. Fadnavis has insisted that talks are ongoing and that the alliance will arrive at a consensus candidate for mayor. However, sharp remarks by BJP leader Ganesh Naik in Shinde’s Thane bastion have underscored the underlying strain, even as the party’s top leadership maintains a more conciliatory tone.

Bal Thackeray’s centenary has amplified the stakes, turning a routine civic power struggle into a contest over legacy, identity, and political relevance. With Shinde seeking to reassert his influence after losing the chief minister’s post in 2024, the BMC mayoral decision could either stabilise the alliance or further deepen the cracks within Maharashtra’s ruling coalition.
