"The greatest contribution of J Jayalalithaa to Tamil Nadu was her immense connect with the people and her model of development was centered around helping poor and marginal sections of the society", ASSOCHAM Secretary General D S Rawat said in a statement.
While Jayalalithaa looked after the marginalised sections through her schemes, Tamil Nadu under her administration was among the top destinations of the domestic and foreign investors, he said.
The State has attracted huge investments in electronics, glass and tele-communication in recent years, he said.
