The King toasted his absent grandson Prince Archie on his fourth birthday at a family celebration in Buckingham Palace after the coronation, the Daily Mail has reported.
Charles also raised a glass to Prince George, Princess Charlotte and Prince Louis who were at the Abbey and the post-ceremony festivities in the royal residence.
The monarch is said to have toasted “those that weren’t there” and wished his other grandson a very happy birthday “wherever he was”.
Harry’s troubled relationship with Charles and the royal family hit new lows after he levelled criticism at his relatives in his memoir Spare at the start of the year.
Glasses of champagne and canapes including mini broad bean and tarragon coronation quiches were served in a running buffet at the Palace, the Mail said.
Official photographs were taken by the couple’s favourite photographer Hugo Burnand in the Throne Room and the Green Drawing Room to mark the day.
