Mumbai, Senior Congress leader Prithviraj Chavan on Tuesday claimed that the Dharavi slum redevelopment project in Mumbai was a "big scam" and demanded the Maharashtra government to bring out a white paper on it.

Speaking in the Maharashtra Assembly on the budgetary demands of the revenue department, Chavan said the entire project would be scrapped once the government changes after the state assembly elections in October.

Dharavi is the largest slum cluster in Mumbai.

The Congress and Shiv Sena (UBT), both part of the opposition Maha Vikas Aghadi, are opposing the multi-billion dollar Dharavi redevelopment project being implemented by the Adani Group.

"The Dharavi redevelopment project is a big scam and the state government should come out with a white paper, otherwise the entire project will be scrapped when the next government comes to power in October," Chavan said.

The former chief minister of the state asked whether the recent handing over of dairy land in Kurla for the Dharavi redevelopment project was mentioned in the original tender.

"There is no mention as to which government land is being given for Dharavi redevelopment...be it Deonar, Mulund, salt pan land," he said.

The Congress leader said, "It should be investigated how much loss has been caused to the government's revenue."

He claimed that government land was being given to industrialists at throwaway prices and all the revenue due to the government had been waived off.

The multi-crore Dharavi slum redevelopment project involves transfer of land not to the Adani Group but to Maharashtra government departments, and the Ahmedabad-based group, as a project developer, will build houses which will be handed over to the same departments for allotment.
