KT Rama Rao, former Telangana minister and senior Bharat Rashtra Samithi (BRS) leader, has written an open letter to Congress leader Rahul Gandhi, questioning the party's "double standards" on the Adani Group. Mr Rao, popularly known as KTR, asked why the Revanth Reddy government in Telangana was welcoming Gautam Adani with "open arms" when the Congress was waging a "so-called crusade" against the industrialist in Delhi.
