Lok Sabha Speaker Sumitra Mahajan on Wednesday referred the matter related to a sting operation against certain Trinamool Congress leaders to the Ethics Committee for investigation.
She made an announcement to this effect immediately after the question hour ended.
A sting operation by a news portal in West Bengal allegedly showed several TMC leaders accepting bribery in return for lobbying for a private firm.
The 15-member Ethics Committee headed by BJP vetaran L.K. Advani includes Arjun Meghwal, Kariya Munda (both BJP), B. Mahtab (Biju Janata Dal), Ninong Ering (Congress) and Akshay Yadav (Samajwadi Party).
