The inauguration of the new parliament building this Sunday will also see Prime Minister Narendra Modi install a historic golden sceptre near the Speaker's seat, Union Home Minister Amit Shah said today. This sceptre, Mr Shah said, was handed over to the country's first Prime Minister Jawaharlal Nehru to mark the transfer of power from British to Indians. The Home Minister said this sceptre is called "sengol" - which derives from the Tamil word "semmai", meaning "righteousness".
