If the swearing-in of a chief minister is anything like the investiture of a beauty queen, Modi will smile in a sash, be hugged by Kamal Nath and commit himself to world peace. This is more or less what he did when he promised to rule on behalf of even those who voted against him.
Narendra Modi favours ceremonial turbans over the tiara; he wears a beard already and the word is that he wants to be known as the Small Sardar. English (because it's foreign) finds it difficult to render metaphorical terms in Indian languages. Small is unsatisfactory for 'Chhote', but Little wouldn't be much better (though Stuart Chhote works quite well) and Sardar Junior (which is closer to the sense of Chhote Sardar) is wrong because it sounds outlandish.
