Congress leader Rahul Gandhi paid a brief visit to the Parliament this morning even as a two-year jail sentence in a defamation case threatens to cancel his Lok Sabha membership. He left after the Lok Sabha was adjourned till noon amid protests. Mr Gandhi, a MP from Kerala's Wayanad, was convicted yesterday and sentenced to two years in jail for his alleged remarks over the 'Modi' surname. A Gujarat court granted him bail for 30 day to appeal the decision.
