The Supreme Court on Tuesday granted bail to BRS leader K Kavitha and asked the ED and the CBI to show what “material” they had to prove that she was involved in the alleged Delhi excise policy scam. A bench of Justices B R Gavai and K V Viswanathan was hearing Kavitha’s pleas seeking bail in the corruption and money laundering cases linked to the alleged scam which are being probed by the Central Bureau of Investigation (CBI) and the Enforcement Directorate (ED) respectively.
