New Delhi, Jan. 20 -- Congress MP Manickam Tagore on Tuesday launched a sharp attack on the Bharatiya Janata Party following Nitin Nabin taking charge as the party's president, alleging that the BJP lacks internal democracy and is run in an authoritative manner.

Reacting to the development, Tagore claimed that key decisions in the BJP are taken only by Prime Minister Narendra Modi and Union Home Minister Amit Shah. Tagore further alleged that the BJP leadership was sidelining its own cadre and concentrating power at the top.
