Delay in finalising seat sharing for the Bihar election adversely impacted the Mahagathbandhan's poll performance, senior Congress leader Tariq Anwar said today, asserting that the Congress must learn from it and complete alliance formalities well in advance for upcoming assembly polls.

Anwar, party's general secretary and a veteran leader from Bihar, acknowledged that there were shortcomings due to which the Congress performed worse than other "Mahagathbandhan" constituents and asserted that the high command was serious about an introspection as well as a thorough analysis of the results.
