Senior Congress leader Kamal Nath, who steered his party to victory in Madhya Pradesh, was on Monday sworn in as its 18th chief minister, bringing to an end 15 years of BJP rule in the state, which had become the saffron party's stronghold.

The former Union minister was administered the oath of office and secrecy by Governor Anandiben Patel at a function held at the Jambori Maidan on a day the Delhi High Court convicted Congress leader Sajjan Kumar in the 1984 anti-Sikh riots, sparking calls that Nath should not be made chief minister.
