The Duke and Duchess of Cambridge wrapped up their successful tour of Britain by Royal Train with a visit to Windsor Castle.

In a heartwarming moment, the Queen joined them to express gratitude to local volunteers and key workers.

This marked the first time the 94-year-old monarch has been seen in public with her son Prince Charles and other senior members of the monarchy since the start of the coronavirus pandemic in March.

Despite the royal couple’s trip being in line with guidelines as they were working, it faced thinly-veiled criticism from Wales and Scotland.

However, William and Kate remained determined to offer support to the nation during their grueling 1,250-mile journey.

Upon their arrival at Windsor Castle, the Queen enjoyed a delightful Christmas carol performance.

The Duke and Duchess of Cambridge were warmly welcomed by Her Majesty, while a Salvation Army band played festive tunes on the steps of the castle.

The Queen, accompanied by her family, could be seen quietly singing along as the joyful melodies filled the air.

Prince Charles, the Duchess of Cornwall, Prince William, Kate Middleton, the Earl and Countess of Wessex, and the Princess Royal stood at a safe distance, taking in the enchanting atmosphere created by nearby Christmas trees adorned with twinkling lights.

Notably absent from the gathering was Prince Philip, who retired from his royal duties in August 2017 and now rarely appears in public.

With his 100th birthday just six months away, his absence was felt.

As the carol performance drew to a close, the Queen, elegantly dressed in an Angela Kelly hat and coat in Christmas red, engaged in conversations with her family members.
