The company also got excess payment against the work executed by them," the ED probe report said."In respect of KK Spun, the company did not fulfil the basis requirement for filing the tender, that is, registration with the irrigation department, and the company was registered with the department after the tender was awarded to the said company," it added. ED sources confirmed that ministers and officials during the SP regime may be summoned for the recording of their statements.TOI has also accessed a copy of the report prepared by the Yogi government, recommending a CBI probe into the project's sanctioned amount from Rs 747.4 crore in February 2015 by the then SP government to Rs 1,990.2 crore in June 2016.
