New Delhi, India (BBN)-India's Prime Minister-elect Narendra Modi has begun a victory parade in Delhi after his opposition BJP party secured the most decisive election victory in three decades.

Modi flew to the capital from his home state of Gujarat, reports BBC.

Current PM Manmohan Singh, whose Congress party was crushed in the poll, is expected to resign later.

Modi, a Hindu nationalist and chief minister of Gujarat, campaigned on promises to revive the economy.

Results show the BJP gained a majority in parliament and will be able to govern without coalition partners.

Make no mistake, the scourge of unrelenting inflation turned the poor and the middle class against Congress: for the last three-and-a-half years India has been suffering its highest rate of inflation for 20 years, one that has also been higher than the world average.

This, many say, was the immediate trigger for people's anger and disenchantment with Congress.

Then there was what many call the party's failure to adapt to a changing India, which was moving, in the words of one commentator, from a "petitional to an aspirational culture".

However, many Indians still have profound concerns over Modi because of claims he did little to stop communal riots in Gujarat in 2002 in which at least 1,000 people died, most of them Muslims.

Modi has always denied the allegations and was never charged.

'INDIA HAS WON'

On arrival in Delhi, Modi was greeted by flag-waving supporters.

Modi stepped out of his car, flashing a victory sign.

At the BJP headquarters – where he is heading to – a brass band, drummers and bagpipers are in place, with bunting and balloons decorating the street.

There is tight security in place along the route of the victory parade.

With votes still being counted, the BJP has won more than the 272 seats needed for a parliamentary majority.

With its allies, the party could get more than 330 seats.

"India has won, good days are about to come," Modi tweeted on Friday as it became clear that the BJP had triumphed.

He later told his cheering supporters: "In the 60-year history of Indian independence, I have never seen this in the Indian media, what you have done in our country."

He said he would rule for all Indians.

"The real government will belong from Kashmir on top to Kanya Kumari [on India's southern tip] – that is a real government.

"The age of divisive politics has ended – from today onwards the politics of uniting people will begin."

World leaders, including US President Barack Obama and UK Prime Minister David Cameron, have congratulated Modi on his victory.

India's new leader has received invitations to Washington and London, despite previously being persona non grata in both capitals following the 2002 riots.

Pakistani Prime Minister Nawaz Sharif commended the BJP's "impressive victory" in the election.

The Congress party, which has dominated Indian politics since independence, is only expected to win 44 seats.

Congress has been mired in serious corruption scandals and its leadership has been considered ineffective in recent years, analysts say.

Accepting defeat, Congress President Sonia Gandhi said: "We humbly respect the verdict of the people."
