ET Online: Glimpse into Prince Harry and Meghan Markle's Strained Relationship with the Royals

Prince Harry and Meghan Markle has endured an intense relationship with the British royal family after stepping down from their roles as senior members of the royal family last year.

Meghan Markle and her husband Prince Harry have endured a difficult year in the media since stepping down from their roles as senior members of the royal family to pursue a more financially independent life.

Sources reportedly said that although the prince has been in touch with his grandmother, the British monarch Queen Elizabeth, his relationship with the royal family has been strained and tense.

The source revealed that the Prince and his wife have ensured that the Queen has access to see her 1-year-old great-grandchild Prince Archie but recent development within Buckingham Palace will not be doing so much to improve their relationship.

It was revealed that Buckingham Palace announced an internal investigation on Wednesday following allegations that Meghan bullied her royal aides which she denied via a spokesperson.

Also, Prince Harry and Meghan's tell-all interview with Oprah Winfrey, which will be airing on Sunday on CBS, will not increase their popularity amongst senior members of the royal family.

The Prince is said to have deep affection and honor for his legendary grandmother, but his latest interview timing might not be perfect.

Royal experts have called for it to be postponed.

According to reports, the father of one has been in touch with the royal family concerning his 99-year-old grandfather, Prince Phillip's health. Prince Harry has been advised to return if possible.

Although there are travel restrictions and regulations, Prince Harry and his family can use a private jet to travel to London to see his grandfather. The condition of the latter is said to be serious.

Some royal family members believe that Prince Harry's interview with Oprah should not be aired on Sunday as planned, seeing that the royal family is in a difficult time.

Royal experts have called for it to be postponed as the royal family is not ready to handle the reactions the interview will generate, seeing that their 99-year-old Prince Phillip is in a grave condition.

According to reports, before news of Prince Harry's interview with Oprah broke, the father of one had a call with his grandmother, the Queen, who told him to uphold the family values.

While the Prince pushed for talks of his exit to be finalized, the Queen asked him to promise not to do anything that would embarrass the royal family or lead to a decline of their public image.

The Queen was reported to have said that she was happy that her young grandson had found happiness and wanted nothing but the best for him and his family in their endeavors.

In the soon-to-be aired interview, Prince Harry and his wife will reportedly chat with iconic TV host Oprah Winfrey for two hours to talk about life in the royal family and their challenges. Fans will be looking forward to it.
