Bhupesh Baghel, the Chief Minister of Congress-ruled Chhattisgarh, has attacked the BJP as "frustrated" after a central agency raided the homes of his party colleagues - ahead of the Congress's plenary session - over alleged corruption in coal levy. "Today the ED (Enforcement Directorate) raided the houses of many of my colleagues, including the treasurer of the Chhattisgarh Congress, the former vice-president of the party and an MLA," Mr Baghel tweeted.
