Even as the Commonwealth Games (CWG) organisers have been struggling to get various projects completed, they now face a new hurdle. Seeking immediate payment of their dues, the contractors working on these projects have threatened to stop work. The contractors working on the projects of Municipal Corporation of Delhi (MCD) related to the Games claimed that their payments totalling over Rs 650 crore were pending with the MCD. Seeking immediate disbursement of their payments, over 200 contractors gathered outside the city town hall on Wednesday. They alleged that they have not been paid for last 18 months to three years for various contracts of MCD. Those working on the CWG projects said they have not been paid for the past five months. As an ultimatum, they have already stalled all civil works apart from the CWG-related projects. Contractors said they have not stopped work on CWG projects yet as it is a matter of national prestige.
