The split in the Opposition ahead of the 2026 Brihanmumbai Municipal Corporation (BMC) elections proved costly for the Uddhav Thackeray-led Shiv Sena (UBT) and the Congress, with vote division directly aiding the ruling BJP and the Eknath Shinde-led Shiv Sena in at least 32 wards across Mumbai.An analysis of candidate-wise voting data released by the Maharashtra State Election Commission (SEC) shows that fragmented Opposition contests helped the BJP win 21 wards and the Shinde-led Sena 10 wards. In one ward, the Ajit Pawar-led NCP also benefited from divided votes, despite not being part of the alliance in Mumbai.In two additional wards, numbers 173 and 225, Sena UBT candidates lost to the BJP after votes were split due to what party leaders described as “friendly fights” involving candidates of the Shinde-led Sena, further damaging the Opposition’s prospects.The vote division followed the breakdown of the Sena UBT-Congress alliance for the BMC polls. Uddhav chose to ally with his cousin Raj Thackeray-led MNS, prompting the Congress to contest independently. The Congress subsequently tied up with Prakash Ambedkar’s Vanchit Bahujan Aghadi (VBA). According to voting data, the lack of coordination among Opposition parties translated into seat losses across multiple wards.Must Read | Maharashtra Corporation Election Results 2026 LIVE Updates: After rout, Congress alleges ‘bogus voting, abuse of power’ by MahayutiIn north Mumbai’s Dahisar West ward number 1, Rakha Yadav of the Shinde Sena won by 2,474 votes over Congress candidate Sheetal Mhatre, who polled 5,070 votes.

When asked whether the alliance break had hurt his party’s performance, he declined to comment. “Cannot speak on ifs and buts in politics,” he said.Story continues below this adSources within the Sena UBT said the alliance with the MNS was necessary to consolidate the Marathi vote. “We cannot decide our political moves based on our ally’s demands. We have to play our politics and they are free to do their own,” a party leader said.Mumbai Congress chief spokesperson Sachin Sawant, however, said the outcome could have been different had the alliance held. “But Uddhavji decided to join hands with Raj Thackeray. It was not possible for us to go with them. We may have suffered more losses had we gone with Thackeray brothers,” he said, adding that the Congress’s decision to contest separately was the right one.
