Princes William and Harry joined by Catherine and Meghan to greet well-wishers at Windsor as they reunite to mourn the death of Queen Elizabeth II

William, Catherine, Harry and Meghan reunited today to display a show of unity and pay respect to Queen Elizabeth II. It is the first time the royal couples have appeared publicly since the passing of Her Majesty, who died peacefully on Thursday afternoon.

• The Queen died at Balmoral age 96 on Thursday afternoon.
• The UK is currently in the second day of a ten-day period of national mourning to mark  Queen Elizabeth II's death. 
• King Charles III confirmed today that her funeral will take place on Monday 19 September.
• Close members of the royal family attended a private church service today. 
• This follows the news that King Charles III has been officially proclaimed as King.

William and Catherine, the new Prince and Princess of Wales, were joined by Harry and Meghan, the Duke and Duchess of Sussex, to view tributes placed by well-wishers, and shake hands with crowds outside of Windsor Castle this evening, Saturday, September, 10.

William, Catherine, Harry and Meghan were all first seen today on the Long Walk at Windsor Castle, as they made their way down together towards the crowds gathered at the gates of Windsor Castle.

The Prince and Princess of Wales and the Duke and Duchess of Sussex spent time looking at the many tributes left to Her Majesty the Queen at the gates, pausing to read notes and cards, and take in the sea of flowers that have been laid on the ground.

Afterwards the four royals made their way over to the waiting crowds and took the time to speak to as many people as possible, shaking hands and accepting bouquets and kind words from those waiting at the gates. One onlooker appeared to give the Prince of Wales a small Paddington Bear toy - a reference to a skit the Queen took part in to celebrate her Platinum Jubilee earlier this year. 

The crowd, who had reportedly been waiting in silence, erupted into roaring cheers when they saw the royal couples, a moment made all the more poignant by the fact that the two brothers and their wives have rarely been pictured together over the last two years.

It is believed, as per The Telegraph, that the Prince of Wales invited Harry and Meghan to join himself and Catherine on the walkabout in Windsor. A Palace spokesperson said, "The Prince of Wales invited the Duke and Duchess of Sussex to join him and the Princess of Wales earlier." 

After spending time speaking to well-wishers, all four royals paused together to thank the waiting crowd one last time before leaving in the same car, driven by William, to head back into the Windsor Estate.

Earlier today, the Prince of Wales gave his first public statement where he paid tribute to his grandmother. In an emotional broadcast, he said she was "at my side at my happiest moments," and "during the saddest days of my life."

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