H Raja, a national secretary of the BJP and Tamil Nadu leader, has drawn flak for posting on Twitter a photo of actor Vijay's voter ID card and official letterhead, his purpose to stress that the popular star is a Christian and his full name is C Vijay Joseph. That, Mr Raja has asserted, is the reason for the actor's latest film Mersal containing dialogues critical of new national tax GST, introduced by the BJP government at the Centre in July this year.
