The Duke of Sussex’s chief of staff has left his role after just three months after mutually agreeing he was not the right fit.

Josh Kettler took up the senior post working with Harry in May ahead of the Sussexes’ tour to Nigeria.

His departure comes as Harry and Meghan prepare for their working trip to Colombia this week.

It is understood Mr Kettler was hired on a trial basis and the decision to part ways was mutual, with both sides agreeing it was not the correct fit.

Harry and Meghan have gained a reputation for being unable to retain staff as they forged ahead with their charitable and production ventures in the US.

Mr Kettler, who was previously chief of staff at communication platform Cognixion, was said to have been brought in to guide Harry through the next phase.

He travelled to London with the duke in May to attend the 10th anniversary celebrations of the Invictus Games at St Paul’s Cathedral.
