There were two main fronts in the election; the alliance between the Congress(R) and CPI and the alliance led by CPI(M). The Congress(R)-CPI alliance was known as the Progressive Democratic Alliance. At the time of the election Indira Gandhi's popularity peaked, with the victory in the
Bangladesh Liberation War and electoral promises of land reform. The
CPI(M)-led alliance included
RSP,
SUCI, RCPI,
MFB,
WPI, the
Biplobi Bangla Congress and some independents. Just before the vote there was a seat-sharing arrangement between the CPI(M)-led alliance and the
AIFB. A minor third front, the West Bengal Democratic Alliance, was led by the
Congress (O) and included
Sushil Kumar Dhara's
Bangla Congress faction, the
SSP rebels and the Indian Awami League. ==Results==
