Prime Minister Narendra Modi is observing a day-long fast on Thursday along with all party MPs in protest against the washout of the recent Parliament session. PM Modi is currently in Chennai to inaugurate a bunch of infra projects in Tamil Nadu. But the Congress has termed the Prime Minister's decision to observe the day-long fast against the disruption in Parliament as 'farce' and demanded that the PM should instead apologise over his party's disrespect to the house.
