In which year was Indira Gandhi expelled from the Congress party by then Congress President S. Nijalingappa for ignoring the 'whip' in the Presidential election?

1969

The correct answer is Option (3) → 1969

This event was a result of a major power struggle between her and the "Syndicate," a group of senior party leaders. The immediate trigger was the Presidential election of 1969. The Syndicate had nominated their candidate, Neelam Sanjiva Reddy, while Indira Gandhi secretly supported the independent candidate, V. V. Giri. Giri won the election, a clear sign of Indira's growing power. In response, the Congress President, S. Nijalingappa, expelled her from the party for "indiscipline." This led to a split in the Indian National Congress, with Indira Gandhi's faction becoming the Congress (R) or "New Congress" and the Syndicate's faction becoming the Congress (O) or "Old Congress."
