While seat-sharing within the Maha Vikas Aghadi (MVA) is nearing completion, there are still nine parliamentary seats yet to be finalised out of the total 48 in the state. Among these, two seats in Mumbai have become points of contention within the India Alliance bloc. Despite Congress failing to secure any seats in Mumbai during the 2019 elections, they now want an equal share in the seat-sharing formula.

Shiv Sena (UBT) is set to contest in South Mumbai and North East Mumbai, while Congress will field candidates in North Mumbai and North Central Mumbai. However, a dispute remains unresolved for the North West Mumbai and South Central Mumbai constituencies.
