DP World's global ports operator has undergone a change in leadership, with the previous head stepping down amidst scrutiny surrounding their association with convicted sex offender Jeffrey Epstein.

Sultan Ahmed bin Sulayem's departure as chairman and chief executive follows the release of newly uncovered files, which indicate he exchanged numerous emails with Epstein over the course of a decade.

The mention of an individual in these files does not imply any wrongdoing, and the BBC has reached out to Sulayem for a statement regarding the matter.

On Friday, DP World announced the appointments of Essa Kazim as chairman and Yuvraj Narayan as chief executive, without making any reference to Sulayem, whose photograph appears to have been removed from the company's website.

DP World, a Dubai-owned logistics company with a significant presence in global trade infrastructure, operating port terminals across six continents, has faced increasing pressure from its business partners in recent days.

Earlier in the week, the UK development finance agency and La Caisse, Canada's second-largest pension fund, announced that they would be suspending new investments in the firm.

Additionally, the Prince of Wales' Earthshot project, which received funding from DP World, was reported to the UK Charity Commission following Sulayem's appearance in the recently released files.

The documents suggest a close and extensive relationship between Sulayem, a prominent Gulf business figure, and Epstein, spanning multiple areas of interaction.

US lawmakers Ro Khanna and Thomas Massie have accused Sulayem of being one of several influential individuals associated with Epstein, citing him as one of "six powerful men" linked to the disgraced financier.

The lawmakers, who co-sponsored the legislation that led to the release of the Epstein files last year, claim that certain information was improperly redacted from the documents.

On 9 February, Thomas Massie highlighted a redacted document that appeared to contain an email from Epstein in 2009, referencing a "torture video"; the recipient responded that they would be traveling between China and the US, although the context of the exchange is unclear.

US officials have confirmed that Sulayem was the recipient of the email in question, which was sent by Epstein.

The complete episode is available for streaming on the BBC Sounds platform.

After a 46-year tenure, the creator of Hello Kitty is relinquishing her design role, marking the end of an era for the beloved character that has become a global phenomenon.

In 1980, Yuko Yamaguchi assumed design responsibilities for Hello Kitty, a character that, despite being commonly perceived as a feline, is actually a little girl from London, five years after the character's initial launch.

During Yamaguchi's four-decade stewardship, Hello Kitty has evolved into one of the most successful franchises worldwide, with its popularity extending far beyond its origins in Japan.

Sanrio, the company behind Hello Kitty, has expressed its gratitude to Yamaguchi, stating that she has "passed the torch" to the next generation of designers.

The launch of Hello Kitty coincided with the rising global popularity of Japanese 'kawaii' culture, a distinctively feminine and youthful aesthetic that has become a cultural phenomenon.

Yamaguchi often embodied the Hello Kitty spirit by wearing dresses inspired by the character and styling her hair in buns, reflecting her deep connection to the brand.

Now 70, Yamaguchi has been credited by Sanrio with transforming Hello Kitty into a universally beloved character, as noted on the company's website.

Sanrio has announced that one of its designers, known by the pseudonym "Aya", who has been working alongside Yamaguchi, will take over as the lead designer by the end of 2026.

Although Yamaguchi is stepping down from her design role, she will remain with Sanrio to offer guidance and support.

Hello Kitty first appeared on a coin purse in 1974, but it was in 1980 that the character began to gain widespread recognition, eventually becoming a global marketing sensation.

The character has been featured on a wide range of products, including clothing, accessories, video games, and even an Airbus plane, and has partnered with notable brands such as Unicef, Nintendo, and Balenciaga, as well as making an appearance as a float in the Macy's Thanksgiving Day Parade.

Hello Kitty-themed cafes can be found worldwide, and there is a dedicated theme park in Japan, with another park slated to open in China.

Unlike other popular Japanese exports, such as Pokemon, Hello Kitty has a relatively minimal backstory, with Sanrio describing her as "not quite a cat, but not a human either".

According to Sanrio, Hello Kitty was born in London, has a twin sister named Mimmy, and a boyfriend named Dear Daniel, although these details are not widely emphasized in the character's marketing.

A Warner Bros film featuring Hello Kitty is scheduled for release in 2028, marking the character's cinematic debut, although she has previously appeared in several animated series, always without speaking, due to her design lacking a mouth.
