A possible CBI investigation against Samajwadi Party chief Akhilesh Yadav triggered huge uproar by the opposition in Rajya Sabha, forcing an adjournment early in the day. The Congress, Mayawati and the Samajwadi Party accused the government of "vendetta politics" meant to block the proposed opposition alliance in Uttar Pradesh. Mayawati later dialled Mr Yadav to show solidarity, saying it was "important not to worry but to fight conspiracies like this".
