Santosh Kumar Singh, a 32-year-old cook, has spent nine years trying to prove to officials that he is alive after his high caste relatives declared him dead following a row over his decision to marry a Dalit woman, known as an “untouchable”. He has written to the prime minister, without success, and has now registered himself as one of 12 candidates for the presidency in the hope that the paperwork will prove his existence. He had left his village in 2000 for a job in Mumbai where he fell in love and married a Dalit woman. When he returned to introduce his new bride to his high cast relatives three years later they told him he was a disgrace and chased him away, he said.
