The Congress-Vanchit Bahujan Aghadi (VBA) alliance for the Mumbai civic polls faces challenges as the VBA has failed to field candidates in 20 of the 62 seats allocated to it. This development, occurring after the nomination deadline, may necessitate a strategy revision for the Congress. The VBA, which draws support from Dalit voters, has returned these seats to its ally, impacting the pre-decided seat-sharing formula for the Brihanmumbai Municipal Corporation elections.
