of courtship, he married Edvige Antonia Albina Màino, who changed her name to Sonia Gandhi and made India her home. Their first child, a son, Rahul Gandhi was born in 1970. In 1972, the couple had a daughter, Priyanka Gandhi, who married Robert Vadra. Entry into politics On 23 June 1980, Rajiv's younger brother Sanjay Gandhi died unexpectedly in an aeroplane crash. At that time, Rajiv Gandhi was in London as part of his foreign tour. Hearing the news, he returned to Delhi and cremated Sanjay's body. As per Agarwal, in the week following Sanjay's death, Shankaracharya Swami Shri Swaroopanand, a saint from Badrinath, visited the family's house to offer his condolences. He advised Rajiv not to fly aeroplanes and instead "dedicate himself to the service of the nation". 70 members of the Congress party signed a proposal and went to Indira, urging Rajiv to enter politics. Indira told them it was Rajiv's decision whether to enter politics. When he was questioned about it, he replied, "If my mother gets help from it, then I will enter politics". Rajiv entered politics on 16 February 1981, when he addressed a national farmers' rally in Delhi. During this time, he was still an employee of Air India. Participation in active politics On 4 May 1981, Indira Gandhi presided over a meeting of the All India Congress Committee. Vasantdada Patil proposed Rajiv as a candidate for the Amethi constituency, which was accepted by all members at the meeting. A week later, the party officially announced his candidacy for the constituency. He then paid the party membership fees of the party and flew to Sultanpur to file his nomination papers and completed other formalities. He won the seat, defeating Lok Dal candidate Sharad Yadav by a margin of 237,000 votes. He took his oath on 17 August as Member of Parliament. Rajiv Gandhi's first political tour was to England, where he attended the wedding ceremony of Prince Charles and Lady Diana Spencer on 29 July 1981. In December the same year, he was put in charge of the Indian Youth Congress. He first showed his organisational ability by "working round the clock" on the 1982 Asian Games. He was one of 33 members of the Indian parliament who were part of the Games' organising committee; sports historian Boria Majumdar writes that being "son of the prime minister he had a moral and unofficial authority"
