KOLKATA, 6 FEB: Kolkata Municipal Corporation will set up a separate cell comprising borough executive officers to oversee development work that are carried out in the slums, member, mayor-in-council (health and bustee), Mr Atin Ghosh, said today. The new cell will prepare a list of the amount spent on slums. Once the KMC has the actual figure of the money spent, it will be easier to prepare schemes, Mr Ghosh added.
