BJP to get absolute majority, won't need regional support: Modi

"I have taken it (moral responsibility for any person killed in Gujarat) since day one. In my speech in the state assembly, all my interviews, speeches, I have mentioned it," he said of the riots in which over 1,000 people, mostly Muslims, were killed.

Asked if his decisions as prime minister would bear an imprint of his background of the Rashtriya Swayamsevak Sangh (RSS), Modi said the government will function "as per the Constitution".

On the question of his wife, which cropped up after he acknowledged his marriage in his election affidavit, Modi said he was not "surprised" at his political opponents tossing up the subject and dismissed that there was anything to discuss about his personal life.
