The man whom we know as Rajiv Gandhi in Public is not the same as who he really was.
One point is clear, what we are told is not, what he is.

Rajiv Gandhi was son of Mohammad Yunus,changed his religion to become a Catholic to marry Sania Maino of Turin, Italy. Rajiv became Roberto.
His daughter’s name is Bianca(priyanka) and son’s name is Raul(Rahul). he mislead people of India that he was a Mechanical Engineer but he not passes a single exam .He gave press conference in London after Prime Minister that he was a parsi but cremated as per vedic rites in full view of India’s public.
From 1962 to 1965, he was enrolled for a Mechanical Engineering course at Trinity College, Cambridge. But, he left Cambridge without a degree because, he could not pass exams. Next year in 1966, he joined Imperial College, London but, again left it without a degree.
“Rajiv first studied at Welham Boys’ School in Dehra Dun, and then went on to the The Doon School. He was sent to London in 1961 to study his A-levels. In 1962, he was offered a place at Trinity College, Cambridge, to study engineering. Rajiv stayed at Cambridge until 1965, but did not complete his degree.[2] In 1966, he was offered and took up a place at Imperial College London, but after a year left that course without a degree.Wiki)
