The Prime Minister's Office has referred the Shunglu Committee findings on alleged irregularities in Commonwealth Games projects by Delhi Government to the Home Ministry for further action.Sources said, PMO has asked Home Ministry to send its reply on the queries raised by the Shunglu panel in works done by the city government controlled departments. In its third report on projects to upgrade city infrastructure, especially related to road and transport, the Committee has noted there was no special preparation by the Government of National Capital Territory of Delhi and blamed Delhi Chief Minister Sheila Dikshit for her decisions that led to cost escalation in CWG related projects.The report said that there was no special preparation despite the constrained time frame. It said that unfair cost advantage was given to contractors due to compressed time frame and noted indication of collusive bidding by tenders floated by Public Works Department (PWD).According to a conservative estimate by the panel, works worth over 5,500 crore rupees were carried out by the GNCTD, a majority of which, about 75 per cent- were executed by PWD.The High Level Committee has held the Delhi Chief Minister responsible for delay in the projects which resulted in high cost. The 235-page report was submitted to PMO on 18th of last month.
