"Took oath of office as Rajya Sabha member representing Uttar Pradesh," Jaitley tweeted, attaching pictures of the oath-taking ceremony held in Rajya Sabha Chairman M. Venkaiah Naidu's chamber in Parliament House here.
Leader of Opposition in the Upper House Ghulam Nabi Azad and several senior BJP leaders, including MPs Bhupender Yadav, Jagadambika Pal, Conrad Sangma and Karnataka's former Chief Minister B.S. Yeddyurappa were also there.
Jaitley was appointed Leader of the House on April 2 but could not take oath as a Rajya Sabha member for the fourth term earlier due to ill-health.
Suffering from a kidney problem, he was admitted to the All India Institute of Medical Sciences here on April 6.
