Angry over lack of progress in developmental work, West Bengal Chief Minister Mamata Banerjee on Wednesday walked out halfway through an administrative meeting in Purulia district."I have walked out half way through the meeting as the work has not been done properly in the district. I have told the Chief Secretary that I won't be conducting the meeting here unless the work is done properly."The state government gave a bunch of instructions to the district administration to complete certain projects for the welfare of the poor people, but those haven't been followed properly. I am very strict in these matters. I won't conduct the meeting here if the work is not complete," she said.The Trinamool supremo, however, did not hold the District Magistrate responsible for the alleged lapses as he has just taken over."The DM of the district has just joined. He cannot be held responsible for this," Banerjee added.
