NEW DELHI (Reuters) - Tens of thousands of Indian farmers and rural workers marched to the Indian parliament in the capital, New Delhi, on Friday in a protest against soaring operating costs and plunging produce prices that have brought misery to many.gi
The protest is one of the biggest displays of frustration with Prime Minister Narendra Modi's government, which faces a tough general election due by May next year. India's 263 million farmers make up an important voting bloc.
"Farmers have been routinely committing suicide," said one of the protest leaders, Yogendra Yadav, as he marched in a crowd down a central Delhi thoroughfare.
"It's a shame that the government doesn't have any time for those who feed us," said Yadav, who leads the Jai Kisan Andolan, a farmers' group.
Low food prices, export curbs, anti-inflation policies that keep rural incomes low and a broad shift from subsidies to investment spending have all infuriated and demoralised farmers.
Agriculture contributes about 15 percent to India's $2.6 trillion economy, Asia's third-largest, but employs nearly half of its 1.3 billion people.
Farmers from more than 200 groups began gathering in New Delhi on Thursday. They are demanding that the government call a special session of parliament to discuss the crisis in the countryside.
"I myself know so many farmers who have committed suicide, and their families are now living in penury," said farmer Lakhan Pal Singh from the northern state of Uttar Pradesh, India's most populous state.
"The policies of the Modi administration are responsible for the plight of farmers."
The discontent in the countryside, where 70 percent of Indians live, could erode support for Modi's ruling Bharatiya Janata Party (BJP), which won India's biggest parliamentary mandate in three decades in the last general election in 2014.
But political analysts and farm economists say Modi will find it hard to repeat that next time.
"We voted for the BJP but anti-farmer policies of the government have hit us hard," said Singh.
Last year, police shot and killed six farmers protesting against lower prices in the central state of Madhya Pradesh, which recently held a state assembly election - a neck-and-neck contest between the BJP and opposition Congress party.
The result is due on Dec. 11.
