Most of the elected members of Shiv Sena took oath in Marathi and started it by hailing Maratha warrior Shivaji and Thackeray. Some hailed Ambedkar, the key architect of the Constitution.
Many of them ended the oath with 'Jai Maharashtra' or 'Jai Maharashtra, Jai Hind'.
With several members deviating from the written script, P A Sangma who was chairing the proceedings, reminded them to strictly stick to the script.
"Follow the script as per the Constitution of India. Do not go beyond what is written," said Sangma, a former Lok Sabha Speaker.
