Delhi chief minister Arvind Kejriwal challenged the Bharatiya Janata Party (BJP) on Tuesday to nominate its chief ministerial candidate and said he was ready for a debate with whomever he chooses. The leader of the Aam Aadmi Party said the opposition party in Delhi would declare the name of its candidate by 1 pm on Wednesday and said that if there is no name by then he would "hold another press conference."The challenge of the AAP chief comes ahead of the elections to the Delhi assembly scheduled for February 8.
