Patna : Factionalism within the Bihar Congress on Wednesday came to the fore at a function to mark the birth anniversary of Indira Gandhi with warring groups organising separate shows here on the occasion. Leaders at the two functions took potshots at their rivals within the party, while stressing on unity to avenge the “insult” to Indira Gandhi by Prime Minister Narendra Modi by not attending her martyrdom day function on October 31. A function was held at Congress headquarters at Sadaquat Ashram, while another was organised at the Miller High School ground. A group within the party is angry with the BPCC chief over appointment of district presidents. Some of them had recently met Congress Vice President Rahul Gandhi and complained against functioning of the PCC President.
