CHENNAI — One of India's most powerful politicians, Jayalalithaa Jayaram, is set to return as chief minister of the southern state of Tamil Nadu following a nine-month break, after a court overturned her conviction in a corruption case. A former film star who has a cult-like following in Tamil Nadu, Jayalalithaa also wields influence in national politics, with her AIADMK party holding the third largest number of seats in India's lower house of parliament. Jayalalithaa is expected to be sworn in as chief minister as early as Saturday. The governor of Tamil Nadu on Friday invited her to form the state government, his office said. — Reuters
