Narendra Modi faces Arvind Kejriwal on final vote day

Voting has begun in the battleground of Varanasi as India votes in the final phase of its mammoth general election.

The main opposition BJP's leader Narendra Modi remains a front-runner in the seat, but is being challenged by Arvind Kejriwal of the new anti-corruption Aam Aadmi Party (AAP).

Voting is taking place in 41 seats on Monday in the states of Uttar Pradesh, Bihar and West Bengal.
