Meghan Markle and Prince Harry 'portraying themselves like royals' as bitter feud continues

However, this has left courtiers in the Royal Family displeased, according to reports.

One former courtier said: "I’m afraid it shows the utter contempt they have for the King and for very long-established ways of doing things.

"Royal tours have always, always been about diplomacy, building bridges and reinforcing friendships on behalf of Britain.

"This tour may well have the noblest intentions, but it is clearly not being carried out on behalf of Britain, and yet they still basically portray themselves as British royals."

They continued to tell The Daily Beast: "It shows you exactly why the royals want these two kept as far away as possible."

Colombia is an unlikely choice for travel as it has one of the highest murder rates in the world.

Only this week, sources close to Harry were claiming his family needs automatic police protection in the UK restored, and blame the King for not delivering it.

However, the Palace has insisted that none of the decisions around Harry's security are personal.

A royal source this week claimed it was "well-established" that "security provision is not decided on by the King" but by the Government.

They added: "For the King himself to attempt to intervene directly in this process in any way would be wholly inappropriate."

However, a Sussex source commented: "If the King wanted, he could do this for his son."

Currently, when visiting the UK, Harry is required to give 28 days' notice to the British security forces of his intention to visit the country, list locations he intends to visit and present a detailed itinerary of his plans.

This suits the Palace, however, a source close to Harry said: "It’s about control."
