The BJP central leadership is "unhappy" with its Bengal unit over its failure to capitalise on the killing of two party workers in Purulia after rural polls in the state, a senior state party leader said Tuesday. BJP national general secretary and in-charge of the state Kailash Vijayvergiya expressed his dissatisfaction during an internal review meeting of the party over the failure of the state leaders to "grab the issue of the killing of party workers" in West Bengal, he said on the condition of anonymity. "Kailash ji has asked us to launch a fresh movement across the state over the violence and attack on BJP workers in the state," he said. During the meeting with the state leaders, Vijayvergiya criticised them over their failure to launch a continuous movement and an agitation on the issue of killing of party workers in Purulia after the state rural polls. "He (Vijayvergiya) said instead of being on the streets on this issue, the state unit was satisfied with just holding a few meetings and rallies. He also asked the leaders the reason why the state unit had failed to launch a mass movement on the issue," a senior BJP leader told PTI on the condition of anonymity. Two BJP activists were found hanging in Purulia district on May 31 and June 2 and the central BJP unit had held a nationwide agitation. BJP national president Amit Shah had also held a rally in Purulia to protest against the killing and had calling for defeating the ruling TMC government in the state. The alleged killings had created a political controversy as the BJP had performed well against the TMC in Balarampur area of Purulia in the last panchayat poll.
