Actor Amitabh Bachchan, whose selection as a host for a mega show to mark the two years of PM Narendra Modi's government has been questioned by the opposition Congress, responded on Friday, saying that he is only going to host a section of the programme. "I've been invited to host a small segment in the programme. I'm attached to a campaign Beti Bachao, Beti Padhao and that is the segment I will be doing. The actual show is being hosted by Madhavan."
