The opposition Congress seems to be facing the heat of the Gujarat Assembly elections as one of the party's important leaders resigned on Sunday. Gujarat Congress spokesperson Rekhaben Chaudhary resigned from the party said reports. Chaudhary tendered her resignation as primary member of the party, spokesperson and all other posts. The resignation comes a few days before the Assembly elections. Political pundits say the resignation is a sign of tension within the Congress which is trying to give a tough fight to the ruling Bharatiya Janata Party (BJP) in the upcoming elections. On Sunday night, the Congress released its third list of 76 candidates for the second phase of the Gujarat polls--the filing of nominations for which ends on Monday.
