TEHRAN, Young Journalists Club (YJC) - Special Rapporteur on extreme poverty and human rights Philip Alston said "harsh and uncaring" austerity policies introduced following the financial crisis "continue largely unabated, despite the tragic social consequences".
"The policies pursued since 2010 amount to retrogressive measures in clear violation of the country's human rights obligations," said the report.
The Conservative government dismissed the findings, calling them a "barely believable documentation of Britain" that painted a "completely inaccurate picture" of the country's welfare system.
Australian lawyer Alston visited Britain in November, and will present his final report to the UN Human Rights Council in Geneva on June 27.
In its summary, he said that "the bottom line is that much of the glue that has held British society together since the Second World War has been deliberately removed and replaced with a harsh and uncaring ethos.
"A booming economy, high employment and a budget surplus have not reversed austerity, a policy pursued more as an ideological than an economic agenda."
He accused the government of being "in a state of denial", saying the motivations behind their policies were not "economic but rather a commitment to achieving radical social re-engineering â- a dramatic restructuring of the relationship between people and the State."
Despite being the fifth largest economy in the world, 20 percent of Britain's people live in poverty, and 1.5 million experienced destitution in 2017, he reported.
"The social safety net has been badly damaged by drastic cuts to local authorities' budgets, which have eliminated many social services, reduced policing services, closed libraries in record numbers, shrunk community and youth centers, and sold off public spaces and buildings," he added.
The report called on Britain to "reverse particularly regressive" welfare measures such as the benefit cap, and reduction in housing benefit.
It also urged the government to restore local government funding.
