Royal protocol Prince George may now be forced to follow after major milestone

Prince George will now be forced to follow a major royal protocol following his 12th birthday. The young royal, who was born in 2013, celebrated his birthday on July 22.

Those in line to the throne have reportedly not travelled together past the age of 12, especially those who are first and second-in-line such as Prince William and his eldest son.

Citing a former royal helicopter pilot, the Daily Mail's Diary Editor Richard Eden said: "When William reached the age of 12, he stopped travelling with his father so they had separate flights. Obviously, that is to guarantee the line of succession." Still quoting the pilot, he then added: "It will be very interesting to see whether that's the case with George and William because we know they have travelled together either via plane, helicopter or car."

Despite this, the Daily Mail's royal editor Rebecca English has since said: "I spoke to the Palace this week, and they were like 'Well, it's kind of news to us''.

"I get the impression that the family won't be changing their travel arrangements at all."

Mr Eden then, after being asked by host Jo Elvin why the protocol is more known about, said it is because they "don't like talking" about security or their travel plans.

He then proceeded to underline what could occur in the event of a tragedy, despite it not being a "tasteful discussion".

Mr Eden went on: "But I have to say, you know, I mean it's not a very, sort of, tasteful discussion, but it's the future of our Royal Family, and I personally find it very worrying. You know, look, after the Wales family, we have Harry and Meghan."

He continued: "The fact is that, you know, Prince Harry and Meghan could be on the throne, and that's something which would be a threat, I would say, to the future of the monarchy."

As well as George, Prince William and Princess Kate have two younger children - Princess Charlotte, 10, and Prince Louis, 7.
