New Delhi, July 14 (ANI): The TRAI Amendment Bill was passed in the Lok Sabha on Monday even as the Congress staged a walkout protesting against it. The Bill seeks to remove a legal hurdle in appointment of former chairman of telecom regulatory body Nripendra Misra as principal secretary to the Prime Minister. The BJP defended the amendment saying it is based on merits while the Congress criticised the government for showing undue haste in bringing a person specific law. The TMC, NCP and the BSP supported the amendment.
