Prince Harry is expected to come back to the UK to attend a ceremony in London on May 8 and whilst the royal is hoping to have his children, Prince Archie and Princess Lilibet, with him, their return is down to one key factor, according to a source.

The Duke of Sussex is set to speak at the Invictus Games 10th Anniversary Service which is to be held at St. Paul’s Cathedral, however, his wife, Meghan Markle’s, attendance is still in doubt, even though she is also listed as a guest at the service with the insider saying her appearance is yet to be confirmed.

And it’s only down to her decision about whether she will return to the UK or not that will determine whether Archie and Lilibet will come back too.

The source explained: “The children’s attendance is still up in the air because they will only visit the UK if their mother [Meghan] decides to attend.”

They added: “Harry is hoping that they will join him so that they can all enjoy the service, and everyone can meet up with members of his family while they are over.”
