The Sussex will separate from the foundation that they created with William and Kate

The Duke and Duchess of Susbad are expected to separate from William and Kate by separating from the Royal Foundation Charitable Foundation.

Only fifteen months after Harry and Meghan made their first appearance to promote the initiative with the Duke and Duchess of Cambridge, they are about to separate.

Last spring, at the foundation's Q & A forum, princes and their wives earned the nickname "Fab Four". The event had to be annual, but it was the first and the only one.

The two couples plan to pursue their charitable interests separately, revealed The Sun.

Aides says this will not be the end of the four mutual support activities on individual projects.

But the goal of the Royal Foundation was to take advantage of the combined quality of the stars of each of its members.

The split follows Harry and Meghan leaving Kensington Palace to settle home away from Kate and William.

The Susbad went to Windsor rather than moving into the neighboring Cambridges apartment.

A source revealed that things had deteriorated between the brothers after the royal wedding.

Another said that couples have only been offered two options with respect to the charity: to continue as is or to separate.

Harry and Meghan moved into Frogmore Cottage (pictured) as they decided to move away from Kensington Palace, where William and Kate live.

Last February, William, Kate, Harry and Meghan received the Beatles' famous nickname as they appeared together on stage to discuss their ideas about the organization, which had been created to advance their charitable ambitions.

They said that "all the ambient music" suggests that the Susbad will break, but nothing has been finalized.

The Cambridges are more constitutionally binding, they added, while the Susesx have more freedom.

A council meeting on June 19 should confirm the split of the Royal Foundation members.

William, 36, and Harry, 34, founded the Royal Foundation 10 years ago to manage their charitable projects together. Kate, 37, joined the team in 2011 and Meghan joined the team last year.

Tina Daheley, the facilitator, asked the two fiancés if they had ever had disagreements.

William replied "oh yes," and when Daheley asked how they had resolved their last disagreement, the prince replied, "Is it resolved? We do not know!

A spokesman for the Royal Foundation told the newspaper: "An examination is underway and no decision has been taken".
