Prince George's godfather has shared some advice for the 12-year-old ahead of his move to Eton College this September. Last month, Kensington Palace announced that the eldest of the Prince and Princess of Wales' three children will be following in his father's footsteps and attending the prestigious Berkshire school, where annual fees are reported to be around £63,000.

While promoting his new book, Beyond the Edge of Light, Jamie Lowther-Pinkerton discussed his godson's new chapter.

Speaking on HELLO!'s A Right Royal Podcast, he shared: "I'm not saying this to lecture poor old George, but I'm saying if anybody goes to that sort of place, then you've got to take the opportunity to live it.

"And actually, dare I say, you've got to then realise how lucky you've been, and you've got to pay back in some way.

"Whether it's through public service, the military or whatever, you've got to pay back. But it is a great privilege, and you don't want to waste it."

Having previously attended the institution himself, Jamie shed light on how it has changed over the years.

"It's probably changed a lot since I went. Actually, it certainly has. And in many ways, it's changed for the better," he added.

"My son was there too, so I've seen it quite recently. You're very, very privileged to go there and there are all sorts of amazing things you can do."

The Prince of Wales attended between 1995 and 2000 but, according to his former classmate, he did not stand out as much as many might expect, despite his royal status.

The ex student, who didn't give his name while chatting to The Telegraph, also claimed William was referred to be a two-word nickname.

"You have to remember that at Eton, he never stood out that much," he shared. "There were boys from even richer families than his, and also boys from very old English aristocratic stock, who could trace their lineage back thousands of years, and who would tease William for being an upstart German.

"We weren't in awe of William, and I don't think he would have wanted us to be."

During the future King's time at the school, the divorce of his parents King Charles and Princess Diana dominated the tabloid headlines. However, according to his former classmate, the subject was rarely discussed among pupils.

The following year, after his mother tragically died in a car crash, hundreds of students reportedly wrote to William to express their condolences. Yet few were willing to raise the subject with him in person.

Last week marked George's final day at Lambrook, a private preparatory school for children aged three to 13 that offers flexible boarding arrangements, which is also attended by his siblings, Princess Charlotte and Prince Louis.

Children aged seven to 13 can board for anything from one night every so often to five nights a week. According to the school's website, there are two boarding houses: Lambrook House for girls and Westfield for boys. Each house is overseen by a house parent and supported by tutors.
