Prince Harry was pictured visiting Pearl Harbor in Hawaii on Remembrance Sunday as the Royal Family gathered in London.

Pictures of the Duke of Sussex, 38, speaking to people at the USS Arizona Memorial in Honolulu were shared online.

He had a poppy pinned to his jacket but chose not to wear his military medals.

The royal was stripped of his right to wear military dress following his departure from the Royal Family – but he is still permitted to wear the medals he earnt for his decade of service in the Armed Forces.

Royal fans commented that it ‘looked like the duke was there for Veteran’s Day’.

He appeared to make the trip alone, leaving wife Meghan Markle and their kids Archie and Lilibet elsewhere.

On the same day, his father King Charles laid a wreath at the Cenotaph in remembrance of all those who died fighting for their country – the first time he has done so as Britain’s monarch.

Harry requested to have a wreath laid in his name at the Cenotaph in 2020 but was reportedly turned down.

Reports initially suggested Buckingham Palace officials had rejected his request. But sources later claimed the Queen herself made the call in the belief Harry should either be ‘in or out’ of the institution and couldn’t ‘pick and choose’.

In a statement posted to their Archewell Foundation website on Sunday, the Duke and Duchess of Sussex said: ‘We honour servicemembers across the world. These brave men and women, as well as their families, have made tremendous sacrifices and embody duty and service.

‘We are proud to work with so many organizations that support veterans and military families, including: The Invictus Games Foundation, The Mission Continues, Team Rubicon, Scotty’s Little Soldiers and The Greatest GENERATIONS Foundation. Today and every day, thank you for your service.’

Harry served in the military for a decade and undertook two tours of Afghanistan.

After leaving the Armed Forces, he set up the Invictus Games for wounded and injured servicemen and women, which has been running since 2014.

This year, Harry also paid tribute to the bereaved children of members of the British Armed Forces.

In a message to charity Scotty’s Little Soldiers, Harry said they are in his ‘thoughts and heart’, telling them they ‘are not alone’.

In 2020, Harry and Meghan ‘personally recognised’ Armistice Day by visiting the Los Angeles National cemetery to pay their respects to fallen Commonwealth soldiers.

They were criticised for arranging a photographer to capture the moment they paid their respects.

The following year they both made a surprise visit to a New Jersey military base, where the duke told service members his years in the army ‘made him’.
