Union finance minister Nirmala Sitharaman was the last to weigh in today on the DMK's move to replace the rupee symbol with the Tamil letter (Ru), but with the sharpest barb. The move, she said, "signals a dangerous mindset that weakens Indian unity and promotes secessionist sentiments under the pretence of regional pride" and is a "completely avoidable example of language and regional chauvinism". She also questioned why the DMK had not made its reservations known earlier.
