The richest 1% of the UK population owns more than 20 times the wealth of the poorest fifth, according to Oxfam.
That made Britain one of the most unequal countries in the developed world and contributed to the vote for Brexit, the charity said.
Its analysis found that about 634,000 Britons were worth 20 times as much as the poorest 13 million people.
The charity’s report analysed data from Credit Suisse and found that the richest 10% of the UK population own over half of the country’s total wealth, with the top 1% owning nearly a quarter (23%). The poorest 20% share just 0.8% of the UK’s wealth between them.
UK one of the most unequal countries, says Oxfam
