Meghan and Harry have 'more experience' at being working royals than Beatrice and Eugenie

Harry's UK return may provide a memory of when he was a working royal, along with his wife, the Duchess of Sussex.

The number of royals who can carry out engagements has become limited in recent years, especially since King Charles has been treated for cancer.

In 2019, Prince Andrew was forced to step down as a working royal and Harry and Meghan left for America the following year.

With the Prince and Princess of Wales also out of action while Kate recovers from surgery, the majority of work will be undertaken by Queen Camilla, Princess Anne, Prince Edward and the Duchess of Edinburgh.

Sources told The Mail that despite the Sussexes stepping down from working royals four years ago, they are the "only available members of the family with any real experience of public duty".

Many commentators have suggested Princess Beatrice, 35, and Princess Eugenie, 33, could be promoted as working royals.

However, they have only performed a small handful of official engagements over the years.

Meanwhile, popular Zara and Mike Tindall are busy with their business ventures and have never carried out royal duties before.

The late Queen's cousins, the Duke and Duchess of Gloucester, the Duke of Kent and Princess Alexandra also perform duties on behalf of the King.

But they are all in their late seventies and eighties, meaning their workload is understandably limited.

With the three most senior royals out of action, the remaining working royals have an average age of 75.

Royal watchers are therefore questioning who could be brought into the Firm to step up, with various younger members looked upon.

While Harry and Meghan are not working royals, the duke remains a counsellor of state, meaning he can work on behalf of the King when he is ill or indisposed.

But the pair have settled in California, where live in a £15million Montecito mansion with their two children.
