New Delhi, Nov 9 (IANS) A day after the BJP and its allies were made to bite the dust in the Bihar assembly elections, the party on Monday began analysing the causes of its rout in the polls.

The polls held significance for the Bharatiya Janata Party as a win could have given it the much needed numbers in the Rajya Sabha.

Prime Minister Narendra Modi reached the BJP headquarters at 11, Ashoka Road to attend the party's top decision-making body, the parliamentary board's meet.

Modi was received by BJP president Amit Shah, who along with others, presented him a bouquet.
