World's richest five men double fortune since 2020, says Oxfam

The world's wealthiest five men have more than doubled their fortune since 2020, the charity Oxfam says, as it calls on nations to resist the ultra-rich's influence over tax policy.

A report from the charity, published as the global elite hobnob at the World Economic Forum (WEF) in Davos this week, said their wealth rose from $405 billion in 2020 to $869 billion last year.
