Kolkata: The Election Commission on Monday said it was looking into a complaint against CPI-M legislator Anisur Rehman for his alleged derogatory comments about West Bengal Chief Minister Mamata Banerjee, even as the state's ruling Trinamool Congress Monday gave notice for a privilege motion against him in the assembly.

The state's joint chief electoral officer Saibal Barman said state chief electoral officer Sunil Gupta was "looking into the matter".
