New Delhi: Former Prime Minister HD Deve Gowda took oath as a member of Rajya Sabha on Sunday after his party nominated him to the Upper House. But his maiden speech as the newly sworn-in member of Rajya Sabha was marred with constant interruptions and the Speaker of the House, Deputy Chairman Harivansh also urged him repeatedly to conclude 10-minute speech, even asking the next speaker to start while Deve Gowda was still speaking.
