The Congress on Tuesday waded into a spat between the AAP and BJP - that the latter, through its Haryana government, had tried to put "poison" in the Yamuna and so contaminate Delhi's water supply.
A Congress delegation met the Election Commission this afternoon to complain against both, demanding action the AAP if the claims are proven false and against the BJP if true.
This was after the AAP's top leaders, including party boss Arvind Kejriwal and Punjab Chief Minister Bhagwant Mann, filed complaints of their own over ammonia levels in the Yamuna.
