South Sudan’s 400 MPs have received a government loan of $40,000 (£30,300) each to buy cars for themselves, causing public anger.
A presidential spokesman defended the $16m expenditure, saying MPs could not be expected to “use motorbikes”.
Critics have accused the government of rewarding MPs two weeks after they voted to extend President Salva Kiir’s term to 2021 reported by BBC.
The government says elections cannot be held because of the ongoing civil war.
More than half South Sudan’s population is threatened with starvation – the food crisis is blamed largely on the conflict which broke out in 2013 between forces loyal to Mr Kiir and his sacked deputy, Riek Machar.
It has forced 3.8 million people to flee their homes, according to the World Food Programme (WFP).
Residents of South Sudan’s capital, Juba, condemned the government for spending the money on cars rather than on development projects.
“Forty-thousand dollars per head is a lot of money. For what kind of transport is that?” one woman told the’s BBC Newsday programme.
“The government is not caring about the situation of people. Is this corruption? Are MPs being given the money to silence them?” she added.

Another resident said some civil servants had not been paid for four months, and the government should have spent the money on their salaries.
Presidential spokesman Ateny Wek Ateny told BBC Newsday that the it had been budgeted for and it was “nonsensical” to suggest that South Sudan’s ruling elite was wasting money.
The MPs would repay the loans over five years, just as they had repaid similar loans given to them in 2005 and 2009 to buy cars, Mr Ateny said.
“Mobility is part of the rights of the parliamentarian,” he added.
