Rahul Gandhi sat in the front with former prime minister Manmohan Singh as he travelled with a busload of opposition leaders to three oath ceremonies, a day after a suggestion that he be the opposition's prime ministerial candidate for the 2019 national polls left many parties cold. "Gathbandhan Travels" missed three prominent passengers - Mamata Banerjee, Mayawati and Akhilesh Yadav -- all of whom have reportedly objected to MK Stalin's proposal that Rahul Gandhi be the joint opposition candidate. But that is not the reason they gave for their inability to attend.
