At Prime Minister Narendra Modi's election rally in Mumbai on Friday, seated in the front row was Anant Ambani, son of India's richest man Mukesh Ambani. "I am here to listen to PM Modi and support the nation", the 24-year-old told a Marathi news channel. The move comes a week after his industrialist father had endorsed Congress's Milind Deora for the Mumbai South Lok Sabha constituency, where elections will take place on Monday.
