Peter Phillips has chosen to part ways as a trustee of the charity after his company SEL UK Ltd was selected to organise The Patron's Lunch to mark the monarch's 90th birthday over fears of a conflict of interest.

A spokesperson for The Patron's Lunch said: "As with any event of this nature, a management fee is standard practice.

"To reiterate, SEL is not taking any share of the profits, which will go direct to The Patron's Fund, simply a fixed rate management fee.

"There would be no Patron's Lunch or Fund had he not come up with the idea and taken it to get approved by the palace in the way he did."

It has been revealed that the son of Princess Anne resigned in November but is currently still a trustee until someone else is found to take on the role.

Meanwhile, Peter previously insisted he "went through the normal channels of approaching the Palace" to organise the event.

He said: "I was very conscious to make sure we did this properly, so we went through the normal channels of approaching the Palace.

"We had to show that this wasn't a case of trying to cut corners because the Queen happens to be my grandmother. I said [to the Queen], 'Oh, by the way you may or may not have heard that we are having conversations with your office about this' ... She said, 'I've heard you're up to something.'"
