Using the PM?

Can the PM's picture  be used in an advertisement announcing the launch of a new commercial service?  Twitter erupted in disapproval on Friday over the full page jacket advertisements for Reliance Jio's  4G services in The Times of India and Hindustan Times which appeared  with a picture of Prime Minister Narendra Modi. The picture appeared under the legend: "Dedicated to India and 1.2 billion Indians".  Is this permitted under the National Emblems law?  Arvind Kejriwal gleefully tweeted: "Any more proof reqd to prove that - मोदी जी अम्बानी की जेब में".
