BJP MP Gautam Gambhir spoke about air pollution in the Delhi-National Capital Region. Gambhir, who has been criticised for missing a parliamentary committee meeting on the crisis, takes a dig at the Arvind Kejriwal government. "The state can no longer get away with a gimmick like odd-even and banning construction sites," he tells the Lok Sabha. "We need long term sustainable solutions and stop the blame game. It's time to own up and act responsibly."
