Vote of No-Confidence
The controversial resignation of the then Home Minister P. T Chacko led to an outburst within the Congress party. With Chacko's failure to win the party presidentship and his subsequent death, 15 Congress MLAs split from the parent party under the leadership of K. M. George. The government which was running on a narrow majority subsequently went on to lose the no confidence motion 73-50.Soon afterwards, dissenters from the Congress party subsequently formed a new party Kerala Congress. This had a major role on the fortunes of the Congress party in the 1965 assembly elections with the Congress securing 36 seats and the Kerala Congress 25 seats. The two parties together garnered nearly 45% of the vote share, evidently showing that a united Congress would have returned to power.
