New Delhi,  Polling to elect the next Vice President of India is underway on Saturday and Prime Minister Narendra Modi was the first to cast his vote in the Parliament House.

"Voted in the 2022 Vice President election," Prime Minister Modi tweeted after casting the vote.

The voting, which began at 10 a.m., will conclude at 5 p.m. After counting of votes in the evening, the next Vice President will be elected.

The Vice President will take the oath of office on August 11, as the term of the incumbent Vice President M Venkaiah Naidu ends on August 10.

Meanwhile, India's second largest Opposition party after the Congress, the Trinamool Congress had decided to abstain from the voting, saying it 'not been consulted' on Margaret Alva's candidature.
