Both Harry and Meghan included in coronation souvenir booklet

Even though she will be absent from the biggest royal event in decades, the Duchess of Sussex has been included in the official program for the coronation. The souvenir booklet is now on sale across the UK and features both Prince Harry and Meghan. But just Prince Harry will make the trip to London for the historic occasion next month, with his wife choosing to stay in California to look after their two children.

That hasn't stopped Buckingham Palace from including a photo of both the Duke and Duchess of Sussex, alongside the Prince and Princess of Wales, King Charles and the Queen Consort. It was taken in 2018, soon after Prince Harry and Meghan's wedding, to mark the 70th birthday of then-Prince Charles. Also in the photo Prince George, Princess Charlotte and a baby Prince Louis.

Behind the lens was Getty's long-time royal photographer Chris Jackson and the image is believed to have been taken at Highgrove House.

Regardless, the photo shows the now King with his two sons and their wives and is one of the final images of the family in happier times.

The 84-page souvenir program costs £37 (GBP20) and went on sale on Monday, weeks out from the May 6 coronation. Jackson also took the photo that graces the cover of the book, that image from the King and Queen's first state banquet hosted at Buckingham Palace in November. The palace has described the book as "celebrating the Coronation of King Charles III and Queen Camilla".

"The 84-page publication is a unique illustrated souvenir that tells the life stories of Their Majesties and offers a preview of the Coronation day, including the service in Westminster Abbey and the historic moment of Crowning," the palace said.

More details about the big day are expected to be shared by the palace in the coming week.

Questions still remain about the dress code, with confusion about whether the royal women will wear tiaras. Foreign royals invited to the coronation at Westminster Abbey are expected to attend a reception with the King and Queen the night before, on May 5. King Willem-Alexander and Queen Maxima of the Netherlands are the latest royals to confirm their RSVP, following a number of other high-profile royals from across Europe.

They include Denmark's Crown Princess Mary and her husband Crown Prince Frederik, Spain's King Felipe and Queen Letizia, Sweden's King Carl XVI Gustaf and Crown Princess Victoria, Monaco's Prince Albert and Princess Charlene, and Japan's Crown Prince Fumihito and Crown Princess Kiko.
