There are more than 18 per cent Hindi-speaking voters in Mumbai who could sway the upcoming elections. To maximise gains from these votes, the Samajwadi Party plans to deploy leaders from Uttar Pradesh to support Congress and the Maha Vikas Aghadi (MVA) in attracting voters in these areas.

Historically, North Indians in Mumbai have been traditional Congress supporters. However, during the 2014 Lok Sabha election, many Hindi-speaking voters shifted to the BJP. According to party data, around seven constituencies have approximately 25 per cent Hindi-speaking voters, while in other areas, they constitute about 15-16 per cent of the electorate. To attract these estimated 20 lakh voters, Samajwadi Party leaders from Uttar Pradesh will come to Mumbai to assist Congress and MVA.
