Lilibet and Archie snubbed as King Charles has 'strained relationship' with Meghan Markle and Prince Harry

Lilibet's snub followed no members of the Royal Family publicly wishing her brother Archie happy birthday on May 6.

RS Locke stated that the birthdays were acknowledged under Queen Elizabeth II due to the cordial relationship the late monarch had with Meghan and Harry.

The royal commentator said: "Last year’s birthday acknowledgement was at the late Queen’s behest and an indication of the cordial relationship she had with Prince Harry, Meghan, and their children."

Locke told the Independent: "King Charles’s decision not to publicly acknowledge his granddaughter’s birthday, nor Prince Archie’s last month, is a reflection of their strained relationship and likely an indication of the social media practices going forward."

Prince Archie's birthday was on the same day as King Charles's Coronation.

But the King reportedly held a toast for the young prince on May 6 following the historic ceremony.

Prince Harry rushed back from the landmark event at Westminster Abbey to the US in order to spend the evening with his son.

Whilst senior members of the Royal Family headed to Buckingham Palace to watch the flypast, the Duke of Sussex darted to Heathrow Airport to catch his flight home.

Prince Harry was in London to testify as part of his phone hacking case against Mirror Group Newspapers (MGN).

The Duke was the first member of the Royal Family to appear in dispatch box since 1891.
