The Sewri and Mahim constituencies will see a showdown between all three Senas. In the former seat, sitting Shiv Sena (UBT) MLA Ajay Choudhari, MNS’s Bala Nandgaonkar and Independent Nana Ambole, who was once a member of the undivided Shiv Sena, will butt heads. In the latter constituency, sitting Shiv Sena MLA Sada Sarvankar, Sena (UBT) candidate Mahesh Sawant and MNS leader Amit Thackeray, son of party chief Raj Thackeray, will face off. 

Mahim

Sarvankar, a three-time corporator and three-time MLA of the undivided Shiv Sena, joined the faction led by Chief Minister Eknath Shinde after the party split. Sawant, now fighting the poll on a Sena (UBT) ticket, started his political career under Sarvankar in the undivided Shiv Sena. Sarvankar is not contesting an election for the first time against Sena (UBT) chief Uddhav Thackeray. In 2009, the Dadar Assembly constituency was merged into the Mahim seat. At the time, a dispute arose between Sarvankar and Mahim MLA Suresh Gambhir over candidature. As a solution, Shiv Sena nominated Marathi actor Adesh Bandekar. Sarvankar then joined the Congress and contested the election. Nitin Sardesai of the MNS, however, won this election. Later, Sarvankar joined the Shiv Sena and became the MLA of Mahim in 2014.
