The growing concentration of the world’s wealth has been highlighted by a report showing that the 26 richest billionaires own as many assets as the 3.8 billion people who make up the poorest half of the planet’s population.

In an annual wealth check released to mark the start of the World Economic Forum in Davos, the development charity Oxfam said 2018 had been a year in which the rich had grown richer and the poor poorer.

It said the widening gap was hindering the fight against poverty, adding that a 1% wealth tax would raise an estimated $418bn (£325bn) a year – enough to educate every child not in school and provide healthcare that would prevent 3 million deaths.
