MUMBAI, June 7 -- The Marathi manoos and attempts to reduce their importance in Mumbai is likely to be the main plank of the Shiv Sena (UBT) campaign strategy for the crucial BMC polls, likely to be held after the monsoon. Given the recent Marathi-versus-Gujarati controversy and the government's attempt to make Hindi a compulsory third language in school curricula, the Shiv Sena (UBT) has planned to focus on its old 'Sons of the Soil' issue and the first right of the Marathi manoos over Mumbai in its poll campaign. Titled 'Ladha Aaplya Mumbaicha' (Battle for our Mumbai), the campaign, according to party insiders, will be led by its youth wing chief Aaditya Thackeray. After the split in the party and losing power to the Eknath Shinde-BJP alliance, Sena (UBT) chief Uddhav Thackeray has been accusing the BJP and particularly Prime Minister Narendra Modi and Union home minister Amit Shah of reducing the importance of Mumbai by shifting establishments out of the metropolis. Thackeray has also opposed the Dharavi Redevelopment Project (DRP) and alleged that Modi-Shah want to gift land across the city to the Adani group in the name of rehabilitation of Dharavi residents. This strategy gave good results to the party, as it won three of the six Lok Sabha seats in Mumbai. Although it lost the assembly elections badly and could win only 20 seats, half of those were from Mumbai, which means the party is still a force in the city. The Thackeray father-son duo is now banking on goodwill from Marathi loyalists to win the BMC polls....
