Union agriculture minister and NCP chief Sharad Pawar on Thursday said an alliance with the Congress was necessary for Brihanmumbai Municipal Corporation elections, due early next year.
He also appointed a committee under chairmanship of Praful Patel to hold talks.
Addressing a meeting of executive committee of Mumbai NCP, Pawar said the alliance was necessary in the interest of Mumbai, and for "providing better life to the citizens".
The committed headed by Patel would talk to the Congress and the decision on whether to form the alliance should be taken within two weeks, he said.
"Deterioration of the standard of living in Mumbai is a cause for concern. Attempts are being made to damage the social fabric of the megapolis, which is known for its multi-cultural and multi-linguistic nature," Pawar said.
City is facing issues such as burgeoning population, infrastructure bottlenecks, poor roads, health, water scarcity, shortage of open spaces, etc, he said.
"There should be a co-ordination between the Centre, the state government and the civic body. The need of the hour is to have a government bound by single ideology. Despite the Centre's and state government's best efforts to improve the condition of the city, the civic body (controlled by Shiv Sena-BJP) is not cooperative," he alleged.
