NEW DELHI (AFP) - An Indian yoga guru on Tuesday ended a six-day hunger strike against corruption but vowed to use his public popularity to pile pressure on Prime Minister Manmohan Singh. Baba Ramdev, a maverick “holy man” who heads a wealthy international yoga organisation, sipped juice to break his fast as several thousand supporters cheered him in New Delhi. Ramdev had tried to lead an anti-corruption march to parliament on Monday but was corralled by police at a sports stadium in the Indian capital. The prime minister “should show political will and honesty, and if he does not show it, he will be deemed as corrupt,” Ramdev, half naked and wearing saffron-coloured robes, told the crowds.
