Ram Nath Kovind was elected Indiainfo-icon's new president Thursday, the second time since independence a head of state has been chosen from the bottom of the Hindu caste system.

Kovind won the largely ceremonial position with more than 65 per cent of the vote by members of India's parliament and state assemblies, the election commission said.

The 71-year-old former lawyer and state governor from the marginalised Dalit community was nominated by Indian Prime Minister Narendra Modi's ruling party for post.

The opposition Congress Party also put forward a Dalit candidate, a former parliamentary speaker Meira Kumar.

But Modi's Bharatiya Janata Party (BJP) assembled enough electoral college votes to push through its candidate and the outcome was expected. Kovind is a longtime associate of the Rashtriya Swayamsevak Sangh, or National Volunteer Corps, a Hindu group that has been accused of stoking religious hatred against Muslims.

"Congratulations to Shri Ram Nath Kovind Ji on being elected the President of India! Best wishes for a fruitful and inspiring tenure," 

Analysts said the election of Kovind would help Modi tighten his grip on power and accrue political capital by sending an important message to the Dalits, a long-disdained electoral group once known as 'untouchables'.

Dalits, who number around 200 million in the nation of 1.3 billion, are among India's poorest communities and relegated to the margins of society.

Despite legal protection, discrimination is rife and Dalits are routinely denied access to education and other advancement opportunities.

Modi had hailed the rise of Kovind, the son of a farmer and former Supreme Courtinfo-icon lawyer, from "a humble background".

India's prime minister wields executive power, but the president can send back some parliamentary bills for reconsideration and also plays a guiding role in the process of forming governments.
