NEW DELHI: Congress General Secretary Priyanka Gandhi Vadra and Robert Vadra's 19-year-old son Rehan, a first-time voter, was conspicuous by his absence on Sunday as his parents came out to vote in the sixth phase of polling in Delhi.

"Rehan cannot vote today as he has gone to London," Priyanka Gandhi told reporters when asked about her son not seen at the polling booth.

Rehan and his sister Miraya had accompanied their parents at the April 10 road show of their uncle Rahul Gandhi in Amethi after which the Congress President had filed nomination papers for the 2019 Lok Sabha elections.

Polling was held for 59 seats in six states and Delhi in the sixth phase of the ongoing Lok Sabha elections. President Ram Nath Kovind, Vice President Venkaiah Naidu, UPA chairperson Sonia Gandhi and Congress chief Rahul Gandhi were among the prominent people who voted in Delhi on Sunday.

External Affairs Minister Sushma Swaraj, Congress general secretary Priyanka Gandhi Vadra, Delhi Chief Minister Arvind Kejriwal, former CM and Congress's North-East Delhi candidate Sheila Dikshit and Airtel Managing Director Sunil Bharti Mittal also cast their vote.

Rahul Gandhi was accompanied by party's New Delhi candidate Ajay Maken to the polling booth while his mother Sonia Gandhi was flanked by Dikshit.

The New Delhi seat is home to many VVIPs, including Supreme Court judges, senior political leaders and top bureaucrats and defence personnel.
