The head of global ports operator DP World has left the company after mounting pressure over his links to convicted sex offender Jeffrey Epstein.
Sultan Ahmed bin Sulayem's exit as chairman and chief executive comes after newly-released files showed the Emirati mogul appears to have exchanged hundreds of emails with Epstein over a decade.
Being mentioned in the files is not a sign of any wrongdoing, and the BBC has approached Sulayem for a comment.
DP World announced his resignation, effective immediately, on Friday, naming Essa Kazim as chairman and Yuvraj Narayan as chief executive. A photograph of Sulayem appeared to have been removed from its website.
DP World, the Dubai-owned logistics giant that runs port terminals across six continents and plays a significant role in global trade infrastructure, has come under increasing pressure over recent days from businesses it works with.
Earlier this week, the UK development finance agency and Canada's second largest pension fund La Caisse said they were suspending new investment into the firm.
And the Prince of Wales' Earthshot project, which received funding from DP World, was reported to the UK Charity Commission after Sulayem appeared in the files.
The documents reveal what appears to have been a close and wide-ranging relationship between one of the Gulf's most influential business figures and Epstein.
Sulayem was also accused by two US lawmakers, Ro Khanna and Thomas Massie, of being one of six powerful men who were associated with the disgraced financier.
The congressmen, who co-sponsored the law that compelled the justice department to release the Epstein files last year, say they were improperly redacted.
According to a BBC News Arabic analysis of the documents, the emails appear to indicate Sulayem appears to have been in contact with Epstein as far back as 2007.
The trail of emails suggest the two developed a close friendship, regularly sending each other their travel plans, business ideas and contacts as well as news articles and crude jokes.
Epstein described Sulayem as one of his most trusted friends in an email from June 2013.
Meanwhile, in several emails over the years, it would appear Sulayem sought Epstein's advice on health matters concerning himself, his daughter and his wider family and friends.
They apparently stayed in touch until at least 2017, two years before Epstein's death and despite Epstein's first criminal conviction in 2008 for soliciting and procuring a person under age 18 for prostitution.
