BJP leader Manoj Sonkar resigned as Chandigarh mayor late last evening, a day ahead of the Supreme Court hearing in the alleged tampering in the mayoral election. He won the poll - seen as the first election battle against the INDIA bloc by defeating the Aam Aadmi Party's (AAP) Kuldeep Kumar - lest than a month ago, on January 30. The BJP secured 16 votes and Kuldeep Singh, the joint candidate of the Congress and AAP was able to manage 12 votes. 8 votes - that became a flashpoint between the BJP and opposition - were declared invalid.
