Congress General Secretary Rahul Gandhi encouraged Congress supporters on Sunday, at a big rally at Delhi’s Ramlila Maidan, defending the UPA government and exhorting the youth to join politics. He also used the opportunity to launch a blistering attack on the opposition for halting the welfare policies of the central government. “The Congress had promised that it would form a government of aaam aadmi and it delivered. From 2004 we have a government that works for the welfare of the poor” said Rahul Gandhi..
