Nandgaonkar, who was minister of state for home in 1995-1999, had hogged limelight after defeating Chhagan Bhujbal (now with NCP but then with Congress) in the 1995 Assembly poll.
South Mumbai is a high-profile constituency having its own share of development issues like inadequate water supply, parking problems, illegal hawkers, contaminated water supply due to intermingling of water and drainage lines and re-development of old and dilapidated buildings.
In 2009 Lok Sabha polls, Deora was believed to have benefited from the vertical split in Shiv Sena votes due to the entry of Nandgaonkar.
He had polled 2.72 lakh votes against 1.59 lakh votes polled by Nandgaonkar and 1.46 lakh by the Sena's Mohan Rawale, while Sanyal secured 10,157 votes.
Rawale was expelled from the Sena last year.
