Janata Party chief Subramanian Swamy today moved the Election Commission to derecognise Congress, alleging the party violated laws by providing a Rs 90 crore loan to a company that published the now-defunct National Herald newspaper. The Congress on its part adopted a combative approach over the controversy on The Associated Journals issue, saying it has discharged its "political dharma" and that it was ready to contest any challenge in any fora for giving loan to support the newspaper.
