A family earning less than $174 a month would receive $87 every month, the opposition Congress chief Rahul Gandhi says.

India’s main opposition party, the Congress Party, will give 72,000 rupees ($1,045) to each of India’s poorest families every year if voted back into power, its chief said on Monday, in what he called a “final assault on poverty”.

Congress President Rahul Gandhi, facing a tough opponent in Prime Minister Narendra Modi in general elections set for April and May, told reporters the programme would benefit 250 million of a population of 1.3 billion.

“It’s an extremely powerful, extremely dynamic, extremely well-thought-through idea,” Gandhi said, calling the programme a fiscally prudent scheme to be rolled out in phases.

“We’ve done all the calculations, we’ve asked the best economists. They all backed us on this idea. We are going to implement it,” he said at a news conference in New Delhi.

A Congress official said any family earning less than 12,000 rupees ($174) a month would receive 6,000 rupees ($87) every month.

Modi’s ruling Bharatiya Janata Party (BJP) dismissed the plan as an enticement on which Congress cannot deliver.

The number of Indians below the poverty line had fallen to about 65 million, or five percent of the population, from 22 percent in 2011, the BJP said on social network Twitter after Gandhi’s news conference.

India is home to about 70 million people living in extreme poverty, which is defined as living on less than $1.9 a day.

The BJP pledged direct cash support of 6,000 rupees ($87) a year for 120 million poor farmers and cut taxes for the middle class last month. It has also rolled out cheap health insurance for the poor.

One analyst said the scheme needed to be designed carefully.

“Large cash-transfer schemes have an important role to play in boosting incomes,” said A Prasanna, head of fixed income research at ICICI Securities in Mumbai.

“However, such schemes will be sustainable in the long run only if they are carefully designed and existing subsidies on food, fuel are subsumed into them.”

Economist and business expert, Aakash Jindal said: “It’s a good concept but Congress should first answer some important questions like ‘what would be the total cost of the scheme? Where would the money come from?'” he said.

Muna Khan, a fruit seller who earns around 9000 rupees monthly and has to feed his family of seven members, welcomed the idea.

“Such a scheme can change our lives. I wish Congress comes to power and the scheme is implemented.”

Echoing Khan’s view, Mohammad Waseem, a vegetable seller who earns between 200 to 300 rupees daily, said that “I will welcome any government who implements such a scheme.”

Ganshyam, who sells snacks in New Delhi’s Khanpur neighbourhood, isn’t hopeful of any such thing. He said: “Congress wants to win the election and that is why Rahul Gandhi is making such statements. We have heard such statements from politicians in past as well but once they come to power no such thing is done by them.”
