The Congress has slammed Vice President Jagdeep Dhankhar over his remarks that people should leave their "political spectacle" behind while embarking on a foreign visit, saying the Rajya Sabha chairman should be impartial and not always praise the government. Speaking at a World Homeopathy Day function here, Dhankhar on Monday said as India lays the foundation for the centenary of its independence in 2047, every attempt that seeks to attack the country's dignity should be blunted.
