Reserve Bank of India (RBI) Governor Urjit Patel resigned on Monday in an abrupt move that followed days of a bitter row between the central bank and the Central government over surplus reserves.

Patel, whose term was to end on September 2019, thus became the first RBI Governor since 1990 to resign from his post.

Among sectors, banks, automobiles, energy, consumption, and metals are the top losers.

The Indian rupee began trading on a negative note on Tuesday, falling over 1.5 percent at 72.46 per US dollar.

Indian markets nosedived earlier on Monday as a result of the exit poll results and weak global cues. Equity benchmarks extended their losses, with the Sensex plunging 600 point slower.
