Home Minister P. Chidambaram, who is known to be fluent in Tamil and English, stunned the Lok Sabha Thursday when he addressed the house in Bhojpuri, receiving praise from Speaker Meira Kumar, who comes from Bihar, for his effort. Chidambaram was replying to a calling attention motion on the need to include Bhojpuri, the native tongue of Bihar, in the Eighth Schedule of the Indian Constitution to accord it the official language status.
