King Charles has reportedly grown tired of Meghan Markle and Prince Harry's "soap opera" dramas after details of the couple's conversation with the monarch on his birthday were leaked.

The 75-year-old King allegedly spoke with his son Prince Harry, 39 and daughter-in-law, Meghan, 42, on his special day last week as the Duchess of Sussex showed him a pre-recorded video of Prince Archie, 4 and Princess Lilibet, 2, singing Happy Birthday to their estranged grandfather.

The phone call made headlines due to the ongoing feud between the father and son that led many to believe they were still not on speaking terms.

Buckingham Palace refused to comment on the "private" call, but it was not long before details emerged, the Mirror reports.

One source close to the monarch told The Sunday Times that the call was a "turning point" in their strained relationship while another claims: "It frustrates him [King Charles] that personal issues intrude on the public duty.

"He’d much rather the focus was on his work, not the soap opera of the private life. It is always frustrating when family dynamics overshadow the public role."

Courtiers were said to be "baffled" that their private conversation was briefed before and after the fact, taking the attention from the actual good work that Charles wishes to highlight as King.

It's not clear how the details of their phone call were leaked but before the reported chat, the BBC reported that it would take place and the Daily Telegraph later reported on specifics from the conversation.

Daily Mail Diary editor Richard Eden questioned how the UK media was able to acquire details of their private call so quickly after it happened.

He wrote for the publication: "How did the BBC know ahead of time that Prince Harry would ring his father?

"And how, afterward, did the Daily Telegraph discover the contents of a conversation to which few others can have been privy?"

Sources close to Harry and Meghan claim the couple want to spend some time with the royals and would readily accept an invitation to Christmas at Sandringham, the King's Norfolk home or a summer trip to Balmoral in Scotland.

A source told the Sunday Times: "I can’t imagine the Sussexes would decline an invitation to spend time with His Majesty.

"As of yet, there have not been any invitations for the holidays."

The Duke and Duchess of Sussex have not spent Christmas at Sandringham since 2018.
