DK Shivakumar, one of Congress's best-known faces from south India, took oath as the Chief Minister of Karnataka today, bringing to an end a long tussle that had made headlines for the better part of two years. His cabinet of 13 ministers - including his predecessor Siddaramaiah's son Yathindra Siddaramaiah -- also took oath on the occasion. G Parameshwara, who served as the state's home minister, took oath as the Deputy Chief Minister.
