evidence: Trinamool Congress MP Shatrughan Sinha on Monday lauded Congress leader Rahul Gandhi’s ‘Bharat Jodo Yatra’ and said he has now emerged as the "frontrunner for the PM post" in the opposition camp. [...] "With due respect to all, I must say the opposition must unite in general and as a nation in particular…When anti-incumbency is rising, and you fail to fulfil your promises, people vote against the ruling party. When we have Rahul Gandhi as a frontrunner and Mamata Banerjee as a game changer, then nothing seems to be impossible," he said. Speaking about differences between the Congress and the TMC, Sinha said he is a "positive person" and hopes that the relation between the two parties would improve in future.
