Union minister Amit Shah said today addressed the hot button issue of delimitation in southern states, saying it would not reduce the number of seats there even by one. "I want to reassure the people of South India that Prime Minister Narendra Modi has kept your interest in mind and will make sure that not even one seat is reduced. And whatever increase is there, southern states will get a fair share, there is no reason to doubt this," he said, speaking at the inauguration of party offices in Coimbatore, Tiruvannamalai.
