MTNL is taking this step as part of its cost reduction measures.

In a filing to Bombay Stock Exchange (BSE), MTNL has stated that given the nil-eligible volume of trading, it is seeking consent of its board members to de-list its securities from Delhi, Kolkata and Chennai Stock Exchange.

However, MTNL in its filing mentioned that the company will continue to be listed on the stock exchanges having nation wide trading terminals through the BSE and the National Stock Exchange.
