New Delhi: In an implicit attack on Finance Minister Arun Jaitley, BJP leader Subramanian Swamy on Friday criticized those "giving me unasked for advice of discipline". "People giving me unasked for advice of discipline and restraint don't realise that if I disregard discipline there would be a bloodbath," Swamy tweeted. Though the MP did not name Jaitley, his tweet followed Jaitley's public admonition of Swamy after the latter called for the sacking of Chief Economic Adviser Arvind Subramanian. Jaitley had said: "The party has said it doesn't share Swamy's view. I will also add one more fact from the point of view of discipline of Indian politicians... to what extent should we attack those, the discipline and constraint of whose offices prevent them from responding and this has happened more than once." In another tweet, Swamy also urged the BJP leadership to ask ministers to wear traditional Indian clothes when they go abroad. "BJP should direct our ministers to wear traditional and modernised Indian clothes while abroad. In coat and tie they look like waiters," he wrote. Jaitley's photographs of meeting with the Bank of China Chairman in Beijing in a lounge suit appeared in several newspapers on Friday morning.
