With months to go for the 2019 general elections, yoga teacher Ramdev, once a staunch supporter of the ruling BJP, has delivered what appears to be a huge rebuff to Prime Minister Narendra Modi. It would be difficult to say who will be the next prime minister, he told news agency ANI on Tuesday. "Now the political situation is very difficult. We cannot say who will [be] the next prime minister or who will lead the country, but situation is very interesting..." Ramdev said in Tamil Nadu's Madurai.
