Indian Prime Minister Narendra Modi's Bharatiya Janata Party (BJP) is on its way to winning parliamentary elections.
The BJP and Congress's main opposition party fought over seven voting phases with strong regional rivals in a bruise campaign.
The results will be announced on May 23. Analysts warn against exit surveys that were often wrong in the past.
Many saw the election as a referendum on Mr Modi, who won a landslide in 201
Four exit polls yielded huge wins for the BJP-led National Democratic Alliance (NDA) and predicted that it would win somewhere between 280 and 315 seats, far more than the opposition congress.
A party or coalition needs 272 to form a government.
India votes 2019
The election began on April 11 and was held in seven phases for security and logistical reasons. With 900 million voters, this is the world's largest exercise in democracy.
The political parties have not commented on the projections so far. However, when the vote ended, there was a flood of opposition leader gatherings that triggered speculation.
What were the main topics of this election?
The economy may be the biggest problem, with agriculture in crisis, rising unemployment and growing fears that India is heading for a recession.
Under Mr Modi, the sixth largest economy in the world has lost some momentum. Growth fluctuates around 7% and according to a leaked government report, the unemployment rate is the highest since the 1970s.
Oversupply of harvests and falling commodity prices have led to stagnant agricultural incomes and burdened many farmers with debt.
Many see this election as a struggle for the identity of India and the state of its minorities. Stricter – and sometimes violent – Hindu nationalism has become mainstream over the past five years, with increased attacks on minorities, including the lynching of dozens of Muslims accused of smuggling cows.
