During a visit last week to Prime Minister Narendra Modi's Lok Sabha constituency, Varanasi, Bihar Chief Minister Nitish Kumar (pictured) said he was more concerned about the Ganga than the central government was. In a veiled attack on Modi, he told a gathering in the city that he was pained to see the Ganga's poor flow in the region. "Who is responsible for this situation," he asked. "We cannot imagine an India without the Ganga. But what is the reason behind interruptions in its flow?" During the 2014 election campaign Modi had promised to work for a clean Ganga and ensure enough water flowed into it.
