It comes after Harry and Meghan Markle were photographed taking part in a small ceremony to honour the UK’s annual commemorations. Pictures show the Duke and Duchess of Sussex at the Los Angeles National Cemetery in California.
There, Prince Harry, dressed in a dark blue suit with military medals attached, gently laid flowers on the ground to pay his respects.
Meanwhile in London, members of the Royal Family took part in a service at the Cenotaph.
Prince William was among those who stepped forward to lay down a wreath in honour of fallen soldiers.
However, Prince Harry’s participation has provoked backlash from some observers who have claimed it looked like a publicity stunt.
Good Morning Britain host Piers Morgan was among them, who took to Twitter to accuse Harry and Meghan of trying to get “media attention”.
A source reportedly close to Prince Harry has hit back at the criticism and denied the Duke’s personal service was to do with publicity.

The Duke is also the founder of the Invictus Games – a sporting competition specifically for wounded servicemen and women.
Supporters of the Duke also took to social media to defend the personal service in LA.
One wrote: “If they hadn’t done something they would be damned, and when they do they are damned.
“The fella served two terms in Afghanistan and set up the Invictus Games.”
Speaking on military podcast Declassified recently, Prince Harry gave insight into his military background.
He said: “Remembrance Day for me is a moment for respect and for hope. Respect for those who came before us and hope for a safer world. Even when we can’t all be together, we always remember together.”
According to The Times, The Duke had asked the Royal Family to lay a wreath at the Cenotaph on his behalf during Sunday’s service in the UK.
However, this request was reportedly refused due to the fact that he no longer represents the monarchy.
He and Meghan stepped back from their senior royal roles in March this year amid their move to the US.
As a result, Prince Harry was forced to give up his honorary military titles.
