The timing is a particular blow to Harry and his wife Meghan as Mr Kettler would have been expected to accompany them on their ‘quasi-royal tour’ of Colombia, which kicks off this week.

When the Duke of Sussex appointed Josh Kettler as his grandly titled chief of staff earlier this year, it was said that he was the perfect man to ‘guide’ Harry ‘through his next phase’.

However, the Daily Mail understands that Mr Kettler has suddenly quit his job after scarcely three months, amid much intrigue.

‘Josh Kettler is no longer working for them,’ a source in California told this newspaper today.

In May, Mr Kettler joined Harry on his visit to London to celebrate the tenth anniversary of the Invictus Games, the sporting event the prince created for injured and sick service personnel.

Later that month, Mr Kettler was a key figure on the Duke and Duchess of Sussex’s three-day ‘tour’ of Nigeria and was by Harry’s side as he met government officials in the West African country. His role on the visit was said to be a foretaste of what he would achieve in the future.

Mr Kettler’s very brief time in his position highlights the difficulties that the Duke and Duchess have had retaining staff.

The total number the Sussexes have lost since they married in 2018 is said to be at least 18, with nine or more having left since they moved to California in 2020.

One former member of staff told the Daily Mail yesterday: ‘What may be most telling is that the entire time I worked there, I don’t think I heard a single current or former employee on their staff say they would take the job again if given the chance.

‘These aren’t employees they had just found off the streets.

‘Many of them are people who had previously excelled working for demanding bosses in high-performance companies and environments.’ Mr Kettler, who is thought to be American, had previously worked for Cognixion, a medical equipment manufacturer.

The Daily Mail Diary reported in April that the Duchess of Sussex had failed to find a chief executive officer for her new cooking and lifestyle business, American Riviera Orchard, despite having interviewed several candidates.

Meghan is said to hope that the brand, which will focus on home, garden, food and lifestyle wares, will be highly lucrative. On Thursday, Harry and Meghan will begin their four-day tour of crime-ravaged Colombia.

Arriving at the invitation of Colombian vice-president Francia Marquez, the pair will, she says, ‘have the exceptional opportunity to engage with elders, youth and women who embody the aspirations and voices of Colombians… and illuminate Colombia’s role as a beacon of culture and innovation’.

The ‘revolving door’ of staff to the Duke and Duchess of Sussex has seen a number of senior figures leave since the couple moved to the US in June 2020.

The departures include Bennett Levine, manager of Archewell Productions, the company Harry and Meghan set up in 2020 to make TV programmes and films, who quit in January. He worked on the Netflix tell-all documentary series Harry And Meghan released in 2022.

Confirming his departure, he said he was moving to Cinetic Media, a US film financing and distribution company.

Fara Taylor was in charge of Archewell’s marketing team before moving to pastures new last year as the couple looked to ‘streamline’. She ran the unit during the release of the Netflix series and Harry’s controversial memoir Spare.

Oscar-nominated producer Ben Browning left as head of internal content at around the same time in January 2023.

Rebecca Sananes quit in December 2022 as head of audio at Archewell, 18 months after being hired to produce the duchess’s Spotify podcast Archetypes.

In the same month, Mandana Dayani stepped down after a year and a half as president of Archewell, which also acted as the couple’s charitable foundation.

An earlier departure was PR chief Toya Holness, dubbed ‘Meghan’s shadow’ as she often wore similar power suits.
