The Congress today alleged that there was diversion of foodgrains in Punjab due to “collusion” between the state government and “food mafia”, leading to heated exchanges between the treasury and opposition benches in Rajya Sabha.Raising the issue during Zero Hour, Congress leader Pratap Singh Bajwa claimed that CAG reports have highlighted diversion of foodgrains and “corruption in government of Punjab” in the distribution.Citing figures, he alleged there was a “collusion” between the state government and “food mafia”.Members from the ruling Shiromani Akali and BJP in Punjab objected to Bajwa’s statement.As the two sides argued, Deputy Chairman PJ Kurien asked Bajwa not to level allegations against anyone.”Allegations not permitted during Zero Hour,” Kurien said and added he would go through the records.However, the Congress member said he was only quoting CAG reports.
