Kolkata, June 16 (IANS) Sovan Chatterjee of the Trinamool Congress was Wednesday sworn in as the new mayor of the Kolkata Municipal Corporation (KMC).

Soon after being administered the oath at the KMC headquarters here, Chatterjee announced he would not charge any water tax from the middle and lower classes and simplify the tax structure.

Deputy Mayor Farzana Alam and other members of the mayor-in-council also took oath.

The Trinamool Congress had made water tax a major campaign plank in the May 30 KMC polls by promising not to levy it if the party came to power.

The 46-year-old Chatterjee has been a KMC councillor uninterruptedly for 25 years since 1985.
