As a pre-wedding gift to the prince, the Queen appointed her grandson a Commonwealth youth ambassador, his most high profile role to as a royal to date.
The newlywed pair attended their first public engagement as a marriage couple in May, as they joined an array of other royals at Buckingham Palace for an early 70th birthday celebration for Prince Charles.
Prince Harry's wife, the Duchess of Sussex - who made her Buckingham Palace balcony debut at Trooping the Colour 2018 - will set off via train with Her Majesty, making their commute on the Royal Train.
It was Queen Elizabeth's official birthday, so the whole family celebrated together with the city. But if Meghan would have had any jitters about what she should wear for these momentous occasions in her short royal life, Prince Harry has ensured the task did not turn too daunting.

The official royal tour will be a rite of passage for royal newcomer Meghan, 36, as she settles into married life with Harry, 33. The Royal Air Force also flew past the crowds leaving behind the colours of the British flag.
Of course, the little girl loosened her control over her younger cousin and enjoyed the event as well at times. That Kate and Queen trip to Leicester came almost a year after her marriage to Prince William.
Andrew took up a more prominent place on the balcony after taking part in his first Trooping the Colour ceremony on horseback in his new role as Colonel of the Grenadier Guards. "She really wants his views", the source said. However, the Mayo News confirmed the Royals were not staying at the famous Ashford Castle in County Mayo since it was booked for a corporate event, reports RTE.
