DHAKA: Polling is underway in Delhi on Saturday in a high-pitched electrifying electoral battle that the national capital has never witnessed before. 

Voters will decide whether to give Delhi a decisive mandate in favour of the Aam Aadmi Party (AAP) or the Bharatiya Janata Party (BJP) - the two front runners -- or keep it a hung assembly even after a year of President's Rule.

Prime Minister Narendra Modi, who added thunder to the BJP's campaign in the national capital, also urged voters to come out and cast their ballot.

"As Delhi votes today (Saturday), urging voters to go out and vote in large numbers," the Prime Minister tweeted.

"I particularly call upon my young friends to vote in record numbers."

Vice-president Hamid Ansari, Congress president Sonia Gandhi, AAP leader Arvind Kejriwal, BJP's chief ministerial candidate Kiran Bedi and Union minister Harsh Vardhan were among the early voters in the Delhi assembly polls.

The elections are significant as a defeat for BJP may bolster the opposition while a victory for the party will increase its confidence ahead of assembly polls in Bihar later this year.

AAP leader Kejriwal, whose party has put up a spirited fight in the polls, cast his vote at around 10am at a polling booth in BK Dutt colony of prestigious New Delhi constituency.
