Stepping up the attack on the BJP ahead of the Delhi Assembly elections, Aam Aadmi Party chief Arvind Kejriwal said the party is not announcing its chief ministerial candidate because it is afraid of suffering defeat. The AAP leader also claimed that the BJP has finalised the name of its former South Delhi MP Ramesh Bidhuri - who was denied a ticket for the Lok Sabha polls but is contesting against Chief Minister Atishi from the Kalkaji constituency in the Assembly polls - as the chief ministerial candidate.
