Trinamool MP Derek O'Brien has been suspended from the Rajya Sabha for the rest of this session for "unruly behaviour", as Parliament resumed amid tension over the major security breach in the Lok Sabha last afternoon. Mr O'Brien had demanded a discussion on the incident, in which two men jumped from the visitors' gallery into the Lok Sabha and burst yellow smoke canisters. An apoplectic Rajya Sabha Chair Jagdeep Dhankhar named the Bengal politician and directed he leave the House immediately.
