The Congress on Thursday urged Prime Minister Narendra Modi to pull up the Gujarat government to come clean on what it said was a "sloppy investigation process" in the Morbi bridge collapse incident.

In a Twitter post, Congress president Mallikarjun Kharge levelled a series of allegations. "Rusted cable of the bridge was NOT repaired. Bridge opened on Oct 26 without fitness certificate and official consent. Contractor was not qualified for the job. Municipality Chief knew that the bridge was open a day before the tragedy," he said.
