UPA Chairperson Sonia Gandhi took oath as member of 17th Lok Sabha on Tuesday.
Gandhi, who retained the Rae Bareli constituency, took her oath in Hindi on the second day of the maiden session of the new Lok Sabha.
Her son and Congress President, Rahul Gandhi appeared to be capturing the moment on his mobile phone from the opposition benches.
While there was a loud thumping of desks by the Congress members, voices were heard from the BJP benches "greeting" Sonia Gandhi "for taking oath in Hindi".
Immediately after her, BJP MP and former minister Maneka Gandhi was administered the oath, and she and her sister-in-law Sonia Gandhi greeted each other with folded hands.
Maneka Gandhi was elected from Sultanpur in Uttar Pradesh. Her son Varun Gandhi, who was elected from Pilibhit, also took oath.
Alphabetical order is followed for states in administering oath to their members.
