Delhi Elections | Arvind Kejriwal News | What's More Toxic, Delhi Air Or Poll Campaign? "Drink if you dare" - Arvind Kejriwal's dramatic response to the Election Commission's demand for proof to back claims the BJP's Haryana government attempted "genocide" by mixing "poison" in Yamuna water supplied to Delhi. "We have four bottles... will send to each one of them... please drink and show us. Then we will believe," he said, pointing to a row of plastic bottles filled, he said, with Yamuna water. Hours earlier the EC directed Mr Kejriwal submit "factual evidence" by 11 am Friday. It also sought answers to five questions, including what kind of 'poison' was used, who detected its presence, and how and where it was found. In its letter, the poll body dismissed last night's submission - a social media post in which Mr Kejriwal cited Delhi Jal Board data that said ammonia levels in the Yamuna had reached critical levels, and that it was "extremely poisonous for human health".
