Prince Harry will return to Britain to celebrate the 10th anniversary of his Invictus Games in May, before joining his wife Meghan Markle on a visit to Nigeria, his spokesperson says.

Harry has returned to Britain only a handful of times since quitting royal life in 2020.

They have included major events such as the funeral of Queen Elizabeth in 2022 and his father the King’s coronation in May 2023.

His spokesperson said Harry would attend a service at St Paul’s Cathedral in London on May 8 to celebrate the Invictus Games, the international sporting event he founded for military personnel wounded in action.

Harry was a military helicopter pilot in Afghanistan and Invictus organisers said the service was designed to mark “a decade of changing lives and saving lives through sport”.

It will include readings by the prince and British actor Damian Lewis. Wounded veterans and members of the Invictus community will also attend.

But Meghan – and the couple’s two young children, Archie and Lilibet – apparently won’t join Harry on his latest visit to his home country.

Instead, the Duchess of Sussex will join Harry in Nigeria for a visit later in May.

Harry’s spokesperson said the couple had been invited by the country’s chief of defence staff, its highest-ranking military official.

That appeared to be confirmed by Nigerian news agency Daily Times.

“The Defence Headquarters has expressed its honour and delight for the acceptance of the Duke of Duchess, His Royal Highness Prince Harry and his wife, the Duchess of Sussex, Meghan to visit Nigeria in May, 2024,” it tweeted on Monday (Australian time).

No further details were given about the trip.

Harry was last seen in Britain in February for a brief meeting with his father after the monarch announced he had been diagnosed with cancer.

Buckingham Palace said on Friday that Charles would return to public duties this week, after making progress following treatment and a period of recuperation.

The King’s first job back after almost three months away from public duties will be a symbolic visit to a cancer treatment centre on Tuesday.

In June, he and the Queen will host the Emperor and Empress of Japan for a state visit.

Harry’s announcement came as elder brother Prince William and wife Kate celebrated their 13th wedding anniversary on Monday (Australian time).

The Princess of Wales, who is undergoing chemotherapy for an undisclosed cancer, married future king William in 2011 after eight years of dating.

The prince returned to work last week, after the Easter holidays when he and Kate spent several weeks’ holiday with their three children George, Charlotte and Louis.

Louis celebrated his sixth birthday last Tuesday and Charlotte turns nine on Thursday.
