It is an usual trend seen in our print and visual media that publicity about any state or central project use to promote any concerned leader or office bearer by displaying his or her photographs or video clips at the cost of our public money... recently such a controversy has been disputed in respect of certain publicity materials of Delhi State Project. Similarly several such publicity have been debated in respect of other state projects of Gujarat, Maharastra, Madhya Pradesh, Rajasthan and even states in India.. The crucial question is that how a leader or office bearer can be promoted by displaying his or her photographs or video clips through state project publicity matters at the cost of public money ?? Can all such state project publicity not been published simply with their respective State Logo without displaying their leaders or ministers or office bearers ? Whether any provisions of law have given them to utilize such public money for self promotion of such the leaders ?? Would it not be misuse of power or misapplication of public fund ??
