Maharashtra Navnirman Sena chief Raj Thackeray raked up the ‘pollution in the Ganga’ row on Sunday. He said he declined to drink water from the river due to medical concerns, pointing to reports of people falling ill after bathing in or drinking it. MNS leader Bala Nandgaonkar had travelled to the recently-concluded Maha Kumbh in Uttar Pradesh’s Prayagraj and brought back some water from ‘sangam’, or holy confluence of Ganga and Yamuna rivers. But Mr Thackerays said he refused the water because he does not think it is sanitary. Shiv Sena MP Priyanka Chaturvedi demanded a response from Prime Minister Narendra Modi and Union Home Minister Amit Shah, and chief ministers of Uttar Pradesh and Maharashtra, both of which are BJP-ruled states. Follows a row last month about high levels of faecal coliform bacteria – a marker of sewage and human organic waste – in water in the river.
