Wild celebrations broke out outside BJP and the Aam Aadmi party offices after the assembly elections results were declared. Workers of the Aam Aadmi Party celebrated the its sensation election debut in the Delhi assembly polls as the party denied the BJP a clear win and decimated the Congress in Delhi. Donning the iconic Gandhi cap with Aam Aadmi Party written on it, the supporters cheered when they came to know that their founder Arvind Kejriwal defeated three-time Delhi Chief Minister Sheila Dikshit in the New Delhi constituency. Meanwhile, Bharatiya Janata Party activists burst firecrackers, beat drums and danced outside the party headquarters in the Rajasthan, Delhi, Madhya Pradesh and Chhattisgarh. In a 'semi-final' verdict ahead of the 2014 Lok Sabha election, the BJP retained Madhya Pradesh and Chhattisgarh, snatched Rajasthan from the Congress but was denied a clear win in Delhi by the debutant Aam Aadmi Party's spectacular showing. So humiliating was the Congress rout in three places -- in Chhattisgarh alone it put up a fight -- that a sombre looking Congress president Sonia Gandhi said that the outcome calls for deep introspection.
