Final voting in mammoth Indian election

The final day of voting has begun in India's general election, with huge crowds turning up in the sacred city of Varanasi, a key election battleground. Opposition BJP leader Narendra Modi is being challenged in the seat by anti-corruption campaigner Arvind Kejriwal. Votes are also being cast in 40 other seats in Uttar Pradesh, Bihar and West Bengal states. The first exit polls are expected on Monday evening. Mr Modi is ahead in all the opinion polls. Votes will be counted on 16 May. India's marathon election began on 7 April and has been held in nine phases for security and logistical reasons. With 814 million eligible voters, it is the world's biggest exercise in democracy and the governing Congress party is battling the opposition Bharatiya Janata Party (BJP) for power, according to BBC.
