The new political battle is over the caste of Narendra Modi, the BJP's prime ministerial candidate. The Congress has alleged that Mr Modi is a "fake OBC." Mr Modi's office says the Congress has "selective amnesia combined with a pathological disdain for the marginalised sections of society."br br The argument has been impelled by Mr Modi's accusation that the Congress' Priyanka Gandhi Vadra derided his background as a member of a lower caste by accusing him of "neech rajniti" or low politics earlier this week.
