Sheikh Tahnoun bin Zayed Al Nahyan, the UAE national security adviser and brother of the country’s president, is among the leading investors backing a new US bank being prepared for launch by Trump family-linked company World Liberty Financial, The Wall Street Journal reported on Thursday.

People familiar with the matter told the newspaper that Tahnoun and other investors are behind an entity that owns 49 per cent — the largest stake — in the holding company established by World Liberty Financial to house its banking project.

Tahnoun backed a $500 million investment in World Liberty Financial last year in exchange for a 49 per cent stake in the company, according to an earlier Wall Street Journal report.
