India's Supreme Court on Thursday moved the rape trial of a powerful regional politician to the capital, New Delhi, to allay fears he could influence the outcome, a further embarrassment for the Hindu nationalist ruling party.

Federal police opened a murder investigation this week against Kuldeep Singh Sengar, a legislator from northern Uttar Pradesh state, after a truck crashed into the car of the young woman who accuses him of rape. Two of her relatives were killed in the crash on Sunday and she is fighting for her life in a hospital.

He denies the rape and any involvement in the car crash.
