Prince William and Duchess Catherine are reportedly feeling frustrated as the saga surrounding Prince Harry and the Home Office continues to unfold.

Sources have revealed that the situation is causing a great deal of frustration for the Duke and Duchess of Cambridge, who are finding the never-ending drama surrounding the former working royals to be too much.

In addition to the controversies, there are also constant legal threats from the Sussex royals' camp, which is causing further stress.

While Prince William is sympathetic to the situation, it is alleged that Duchess Catherine is more worried about Queen Elizabeth II's health.

The British royal family, especially its matriarch, is already dealing with so much turmoil, including issues, scandals, and controversies that continue to emerge one after the other.

Apart from the security concerns that Prince Harry and Meghan Markle have, there is also a lawsuit that Prince Andrew is facing.

On top of these things, the reigning monarch previously had a health scare, causing more concerns to surface.

Furthermore, the Windsor-Mountbatten clan lost its patriarch last year when Prince Philip passed away at the age of 99.

Insiders have asserted that the Harkless's timing is just appalling, as always.

A tabloid reports this week that the third-in-line to the throne doesn't want his embattled sister-in-law swallowing back into the UK and taking over the headlines during an upcoming momentous event for the royal family.

Apparently, Meghan is facing some unwelcome consequences after dragging the royal family through the mud last year.

According to sources who spoke with the outlet, Queen Elizabeth put William, along with a few advisers, in charge of crafting the guest list for her Platinum Jubilee celebrations.

William quickly made use of his new powers by making it clear that Markle was definitely off the list.

A source confides, “Meghan's made things hard enough, without her swallowing back into the UK and having all the headlines be about her again,” adding, “Wills just doesn't want the drama she always seems to bring.”

This is supposedly the last news that Markle wanted to hear.

Meghan can't bear the thought of how humiliating it would be if people found out she wasn't invited, a source allegedly close to the California-based duchess explains.

Now Markle is desperately backpedalling, but it would seem she's just uselessly spinning her wheels.

She's trying to reach him but is being stonewalled by his staff.

William has made it clear the damage is done and he has no interest in speaking to her, the tipster gleefully reports.

This is a catastrophe for Meghan, the source continues, adding that Markle has realised she still needs to be connected with the royal family to keep her high profile, as public interest in her and Prince Harry wanes in the US.

The suspicious source insists that Markle is now worried that William has more sway with his grandmother than she realised and is fretting that he'll do something drastic like convincing her to cut off Harry and Meghan, both from herself and her fortune.

Meanwhile, Duchess of Cambridge and her husband William will attend an engagement at BAFTA's headquarters in London on Thursday, just days before the Queen prepares for a difficult anniversary.

The couple will mark the reopening of the British Academy of Film and Television Arts headquarters by visiting their refurbished building later this week.

While there, the royal couple will learn about BAFTA's efforts to increase the amount of support given to young people aspiring to work in the film, games and television industries.

The purpose of the Academy's annual awards is to recognise, honour and reward individuals for outstanding achievement in feature films released in the UK within the awards year.

The Duke of Cambridge has been President of BAFTA since February 2010, a post previously held by both his grandfather Prince Philip and his aunt Princess Anne.
