Prince William and Harry and their wives Kate Middleton and Meghan Markle have set their differences aside and reunited in a remarkable 40-minute walkabout inspecting the sea of floral tributes outside Windsor Castle.

In an unexpected show of unity, the Prince and Princess of Wales and the Duke and Duchess of Sussex, all dressed in black, went to talk to well-wishers and look at flowers from those who had come to remember the Queen.

Harry and Meghan held hands as they walked together while crowds cheered.

The four walked together to meet and greet mourners - Harry and Meghan had apparently been invited by the newly minted Prince of Wales to join him and Kate. Royal watchers have described it as a "significant moment" for the two brothers and may signal the end of their feud.

The Sussexes' friend and royal reporter Omid Scobie claimed on Twitter that the invitation was made at the '11th hour'.

"It is, without a doubt, a significant moment in the history of the relationship between the two brothers," Scobie said.

This is reported to be the first time the two couples have all been in public together since Commonwealth Day on March 9, 2020.

The public in Windsor was reported to be delighted to see the couples have put aside the differences which have fractured the Royal Family and seen Prince Harry and Meghan relocate permanently to the US.

A royal fan who spoke to Harry and Meghan told Daily Mail: "It's lovely to see them both together. Maybe they can get back to a proper relationship. Lovely ripple went through the crowd as they approached. Hopefully the healing between Harry and his brother can start now. I'm just so excited to have seen them both together. It's lovely."

The appearance is thought to be the first time that the two couples have all been in public together since Commonwealth Day on March 9, 2020.

For Meghan Markle, the walkabout signalled another step in her extraordinary re-emergence in the Royal Family following the death of the Queen.

The Queen's death has been a rollercoaster ride for Meghan Markle.

It had been reported she was initially planning to rush up to Scotland, with Harry, to be by the Queen's side.

King Charles reportedly then had a phone conversation with Prince Harry advising him not to bring his wife to Balmoral.

A source told The Sun: "Charles told Harry that it wasn't right or appropriate for Meghan to be in Balmoral at such a deeply sad time.

"It was pointed out to him that Kate was not going and that the numbers really should be limited to the very closest family. Charles made it very, very clear Meghan would not be welcome."

Just a week before the Duchess had given a tell-all interview to magazine The Cut in which she had suggested that the Duke had "lost" his father.

However, in his first speech, the new King warmly mentioned the Sussexes.

"I want to express my love for Harry and Meghan as they continue to build their lives overseas," King Charles said.

The Sussex children also received new royal titles. They are now known as His Royal Highness Prince Archie of Sussex and Her Royal Highness Princess Lilibet of Sussex.

As grandchildren of King Charles, the couple's children Archie and Lilibet now have the right to be a prince and princess, which they did not before as the Queen's great grandchildren.

That was said to have blindsided Markle who wasn't aware her children's titles would change and left her in an awkward position given past suggestions Archie would be denied a title due to racism within the Royal Family.

Meanwhile, Prince William has issued a touching tribute to his grandmother, Queen Elizabeth.

Taking to Instagram with the couple's newly assumed titles, Prince and Princess of Wales, William told royal followers of his grief for the historic monarch.

"On Thursday, the world lost an extraordinary leader, whose commitment to the country, the Realms and the Commonwealth was absolute. So much will be said in the days ahead about the meaning of her historic reign," he said.

Adding: "I, however, have lost a grandmother. And while I will grieve her loss, I also feel incredibly grateful. I have had the benefit of The Queen's wisdom and reassurance into my fifth decade.

"My wife has had twenty years of her guidance and support. My three children have got to spend holidays with her and create memories that will last their whole lives.

"She was by my side at my happiest moments. And she was by my side during the saddest days of my life.

"I knew this day would come, but it will be sometime before the reality of life without Grannie will truly feel real."

"I thank her for the kindness she showed my family and me. And I thank her on behalf of my generation for providing an example of service and dignity in public life that was from a different age, but always relevant to us all.

"My grandmother famously said that grief was the price we pay for love. All of the sadness we will feel in the coming weeks will be testament to the love we felt for our extraordinary Queen.

"I will honour her memory by supporting my father, The King, in every way I can."
King Charles bestowed the couple's new titles on them yesterday as well as his wife, Camilla's new title of Queen Consort.

As the King took on his new responsibilities as monarch, he told the nation, "As my Heir, William now assumes the Scottish titles which have meant so much to me. He succeeds me as Duke of Cornwall and takes on the responsibilities for the Duchy of Cornwall which I have undertaken for more than five decades."

"Today, I am proud to create him Prince of Wales, Tywysog Cymru, the country whose title I have been so greatly privileged to bear during so much of my life and duty," he added.

"With Catherine beside him, our new Prince and Princess of Wales will, I know, continue to inspire and lead our national conversations, helping to bring the marginal to the centre ground where vital help can be given."

The couple were formally known as the Duke and Duchess of Cambridge.
