Ram Nath Kovind has filed his nomination papers for the Presidential polls.
He did so in the presence of Prime Minister Modi, BJP president Amit Shah, and a phalanx of other leaders.
"I am thankful to all those who have supported me, will try to maintain the dignity of the post," Kovind said after filing his nomination papers.
Media reports said the prime minister was first proposer on Mr Kovind's nomination and union home minister Rajnath Singh second.
Bihar chief minister Nitish Kumar has broken ranks with the Opposition, pledging support to Mr Kovind.
The picking of Mr Kovind as NDA candidate had stunned the Opposition, with a number of them saying it would be difficult to oppose a Dali.
The Congress and Opposition have picked former Lok Sabha speaker Meira Kumar, who is also a Dalit, to contest against Mr Kovind.
This then becomes a Dalit vs Dalit battle.
But the National Democratic Alliance now has over 60 per cent of the vote and Mr Kovind is expected to sail through.
Ms Kumar is expected to file her nomination papers in a few days.
