And an interesting read from the Indian Express last week, from a column by Coomi Kapoor.

"In Gujarat, Modi kept a close watch on what his Cabinet colleagues and others in the party were up to. The PM seems to have developed an effective feedback mechanism in Delhi as well. Recently, the son of a minister was reportedly asked to come to Modi's residence. The PM praised him for his good work, but then slipped in a remark that had the young man rattled. Modi said it had come to his knowledge that some money had exchanged hands for the posting of an official. Modi asked him to return the money. The son and his father certainly got the message."
