King Charles had a very big day yesterday as he celebrated his 77th birthday. While many people like to put their feet up and relax on their special day, the monarch did the opposite, and instead had a busy day carrying out engagements in Wales.

Throughout the day, the King was given plenty of warm birthday wishes, both during engagements and online. This included a sweet public birthday message from his oldest son Prince William and William’s wife Princess Catherine.

They wrote: “Happy birthday to His Majesty The King!”

However, there was one noticeable public birthday greeting missing.

While his youngest son Prince Harry and his wife Meghan Markle could, and are likely to have, sent the monarch private birthday wishes, they did not do so publicly.

This is despite the fact Meghan, 44, often uses the personal Instagram account she launched this year to celebrate the birthdays of family members, including her husband Prince Harry and their children.

As well as not posting anything about King Charles’ big day online, Meghan did not address anything about her father-in-law’s birthday either – which may not be unusual, as she tends to only publicly mark the birthdays of her nearest and dearest.

She simply stayed radio silent on Instagram, with her last post being just days ago for Veterans Day.

It is not known when Meghan last saw King Charles, with her last visit to the UK being in September 2022.

It is believed that Prince Harry, Meghan’s husband of seven years, is on good terms with his father, with the pair having reconciled just months ago after having not seen each other since February 2024.

After being reunited with his dad, Harry, 41, said his father would be his “focus” over the next year, suggesting that the prince’s relationship with the King – which has had some challenges since Harry walked away from royal duty in 2020 – is a priority for him.
