In a double whammy for the Shiv Sena in its home turf – Bandra East – they not only lost the seat but also the party's face when voters rejected Mumbai's first citizen, Mayor Vishwanath Mahadeshwar, who was contesting from the constituency. Trupti Sawant, a Sena rebel, who contested as an Independent candidate, played a spoilsport leading to the victory of Congress candidate Zeeshan Siddiqui, son of former MLA Baba Siddiqui.

After holding on to the Bandra East for two successful terms, Sena lost it in a close fight to Congress. It took 14 rounds of counting before Siddique could move ahead of Mahadeshwar. In the initial rounds of counting, Mahadeshwar's lead continued to grow, with a margin of 5,545 votes in the ninth round, after which it dropped to a margin of 842 votes in the 13th round. Siddiqui defeated Mahadeshwar in the 19th round with 38,337 votes while Mahadeshwar bagged 32,547 votes.
