Besides, there will be Delhi Chief Minister Arvind Kejriwal and representatives of other constituents of the INDIA-MVA alliance.
In addition, other senior MVA leaders like Nana Patole, Sanjay Raut and Jayant Patil are expected to speak at the rally, coming just three days ahead of the fifth phase of Lok Sabha polls on May 20, covering 13 constituencies, including the crucial Mumbai Metropolitan Region.
An MVA leader claimed that Friday's rally would be the biggest combined opposition show of strength in the state since the poll campaign started and people are expected to participate from all over the state.

In the last two months after the Lok Sabha elections were announced on March 16, INDIA-MVA top leaders have addressed several rallies, public meetings across Maharashtra in the 48 Parliamentary constituencies - the second highest in the country.
They included Kharge, Rahul Gandhi, Priyanka Gandhi, Sharad Pawar, Thackeray and other senior leaders of various parties canvassing for the alliance and respective party candidates in the state.
So far, in the past four phases of elections in Maharashtra, voting was completed for 5 seats (April 19), 8 seats (April 26), 7 constituencies each (May 7 and May 13), while the final and biggest round of voting for 13 seats is scheduled for Monday (May 20).
